And minus 3 plus 19 is plus 16x.

Minus 5 plus or minus the square root 25 plus 288 is 313 I believe.

Too many plus minus symbols

Well five minus negative three, that's five plus plus three.

3 plus or minus the square root of 33 over minus 6.

That's 9 plus or minus the square root 81 plus 216.

So plus or minus 11 12. Right?

Well, that's equal to minus 5 plus or minus the square root of 25.

Let's say I wanted to solve minus 8x squared plus 5x plus 9.

So we get x plus 8 is equal to plus or minus 11.

Plus or minus the square root of 81.

And so x is equal to subtract 8 from both sides minus 8 plus or minus 11.

And we get x minus 7 12 is equal to the plus or minus square root of that.

So let's say I had the equation minus 9x squared minus 9x plus 6 equals 0.

Well that equals 7 plus or minus 11 12.

And so x could equal so minus 8 plus 11 is 3.

The figures may bear plus or minus 15 per cent inaccuracy.

One of them is x is equal to minus 5 plus the square root of 313 over minus 16.

Right? Let me make sure I did that right. x is equal to minus 8 plus or minus 11.

And you might want to think about why we have that plus or minus.

So this is equal to 9 plus or minus 3 times the square root of 33, and all of that over minus 18.

In appearance, he resembled Mahatma Gandhi, minus the loincloth, plus orthopedic boots.

You know, x plus some integer or x minus some integer times, you know, x plus some other integer.

So this is the same thing as 9 plus or minus the square root of 9 times 33 over minus 18.

We get once again, arbitrarily switching colors that x plus 8 is equal to, and remember this, the plus or minus square root of 121.

They have 22 satellites zipping around at plus or minus 100 miles, and the site's in red.

The quadratic equation says, if I'm trying to solve the equation Ax squared plus Bx plus C equals 0, then the solution or the solutions because there's usually two times that it intersects the x axis, or two solutions for this equation is x equals minus B plus or minus the square root of B squared minus 4 times A times C.

Plus or minus the square root of B squared, so that's 81. Right? Negative 9 squared.

One x value is x equals 3 plus the square root of 33 over minus 6.

So negative 5, plus or minus the square root of B squared that's 5 squared, 25.

So let's say I have this equation x squared plus 16x minus 57 is equal to 0.

But what we've said, I know you might have lost track we did all this math is we said, this equation minus 9x squared minus 9x plus 6.

In 2001, 1829 HIV AIDS cases were reported at health facilities, and then analyzed at the coordination headquarters of the national AIDS campaign 989, or 54 per cent, of these patients were women. The average age of a person with HIV is 34 plus or minus 22 years 32 plus or minus 18 years for females, and 39 plus or minus 19 years for males. Of the 1829 HIV cases, 1027, or 56.20 per cent, were asymptomatic.

We have that plus or minus because a square root could actually be a positive or a negative number.

A flexibility factor of plus and minus 15 per cent is then calculated to determine the upper and lower limits of the particular desirable range.

Essentially, 4 minus 1 and getting 3 is the exact same you're saying the same thing as 3 plus 1 is equal to 4.

So in theory this should be able to be factored as x minus 3 times x plus 19 is equal to 0.

And then if I took minus 8 minus 11, x could also equal minus 19.

And so we know that this left hand side of this equation is x minus a or x plus a, but a is a negative number.

So then we could add 7 12 to both sides of this equation, and we get x is equal to 7 12 plus or minus 11 12.

Minus 3 times 19 is minus 57.

And the other one is x is equal to minus 5 minus the square root of 313 over minus 16.

All we have are comparisons between what happened at different times. What these comparisons show is that markets plus government have done better than markets minus government.

So we have x squared I'm just going to open up some space minus 7 6 x plus something is going to be equal to 1 2.

Minus
