2/9 (9/4x-9) pls i’ll mark u brainless!

1/2x-2

Step-by-step explanation:

First you do distributive property

2/9*9/4x-2/9*9

If you simplify that you get 1/2x-2, that is thhe same as x/2-2

a=4  b = -16  c=9

Step-by-step explanation:

4(x-2)^2 -7

We need to FOIL out the (x-2) ^2

( x-2)^2 = (x-2) (x-2) = x^2 -2x -2x+4 = x^2 -4x+4

Replace this in the equation

4( x^2 -4x+4) -7

Distribute

4x^2 -16x +16 -7

Combine like terms

4x^2 -16x +9

a=4  b = -16  c=9
