The factored form of 9x^2 + 12x + 4 is:
(3x+2)(3x+2) or (3x+2)^2
Answer:
(x+6)(x+2)=60
expand
x^2+6x+2x+12=60
x^2+8x+12=60
minus 60 both sides
x^2+8x-48=0
factor
what multiplies to -48 and adds to 8
-4 and 12
(x-4)(x+12)=0
set each to zero
x-4=0
x=4
x+12=0
x=-12
x=4 or -12
Step-by-step explanation:
You cant solve y but you can form an equation in terms of y
which is y=7-2x
if you were given another equation that has the term y and x than you can solve it.also that is a simultaneous equation.
Hope this helps,dont forget to put this as the brainliest answer if it does to help me out too. xD
