Answer: CHOICE NUMBER 4: x = 3/2 or -1
Step-by-step explanation:
2(x+3)+(−3x)(x)=x*x
−3x^2+2x+6=x^2(Simplify both sides of the equation)
−3x^2+2x+6−x^2=x^2−x^2(Subtract x^2 from both sides)
−4x^2+2x+6=0
−2(2x−3)(x+1)=0(Factor left side of equation)
2x−3=0 or x+1=0(Set factors equal to 0)
x = 3/2
or x=−1
Plug them into the equation and it works!
Hope this helps! :)
