Factor. z^2 -6z -16 simplify

1 answer:

3 0

(z-8) (z+2)
What I do to factor is find _x_=-16 and _+_=-6. -8x2=-16 and -8+2=-16. The coordinates for z if you were to graph this would be (8,0) and (-2,0)

Expand and simplify: (-7y - 8) (y - 4)

maks197457 [2]

Answer:

${ - 7y}^{2} + 20y + 32$

Step-by-step explanation:

1.) -7y times y = -7y(squared)

2.) -7y times -4 = 28y

3.) -8 times y = -8y

4.) -8 times -4 = 32

5.) Combine like terms

${ - 7y}^{2} + 28y - 8y + 32 = { - 7y}^{2} + 20y + 32$
