1) (6z-u)(6z+7u)

Question

how do I Find the product for this?

I have 36z^2+36zu-7u^2 is that correct?

2) Also how do i complete the ordered given pairs for the equation x-3=0

Y is 4, 1, -3 what is x?

Answer 1

The first 1 is correct

For the second problem, You should make an x and y chart I THINK.

Answer 2

Thanks. What about find the slope, if it exists, of the line containing the given pair points

(-17,-3) and (-20,-9)

The slope M=

is this 2x+31 or 2x or just 2?

Answer 3

The formula to find that is
y2-y1/x2-x1

(-9 + 3)/(-20 + 7 )

-6/-13

6/13 << that is the slope

Answer 4

Okay, One last question. Perform the indicated operations

(9x^2-7x-66)(+8x^2+9x)

is this answer 17x^2+2x-66

Answer 5

8x^2(9x^2 - 7x - 66) + 9x(9x^2 - 7x - 66)

72x^4 + 25x^3 - 591^x2 - 594x

I could be wrong on this one
