Solve the following quadratic equation for all values of x in simplest form.
3(x + 8)2 – 20 = 28

Step-by-step explanation:

3(x+8)²-20=28

3(x+8)²=28+20

divide by 3

(x+8)²=48/3=16

x+8=±4

either x+8=4

x=4-8=-4

x=-4

or x+8=-4

x=-4-8=-12

x=-12

true? is that what you're asking or do you mean something else?

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8
