Answer:
4x^2 +12x +9 -25=0
4x^2+12x-16=0
(2x+8)(2x-2)=0
2x+8=0 2x-2=0
X=-4 X=1
Step-by-step explanation:
Remember, we can do anything to an equation as long as you do it to both sides
and distributive proeprty, reversed
ab+ac=a(b+c)
xm=x+z
minus x from both sides
xm-x=z
xm-1x
undistribute x
x(m-1)=z
divide both sides by (m-1)
Answer:
7 + 6x
Step-by-step explanation:
12 + 3(2x - 3) + 4 =
12 + 6x - 9 + 4 =
7 + 6x
