Answer:
<h2><u><em>
x=3 or x=−4</em></u></h2>
Step-by-step explanation:
when a number x is added to it's square, the total is 12. find two possible values of x
x+x^2=12
x^2+x=12
x^2+x−12=12−12
x^2+x−12=0
(x−3)(x+4)=0
x−3=0 or x+4=0
x=3 or x=−4
x=3 or x=−4
(-2 x -3) - (3x^2 - 8x + 9)
-6 - 9x - 17x
-6 - -8x
-14x
