Answer: -4
Step-by-step explanation:
p(x)=x^3+3x^2+ax-12
x+3 is factors means it divide completely so x=-3
p(-3)=(-3)^3+3(-3)^2+a(-3)-12
-27+27-3a-12=0
-3a-12=0
3a=-12
a=-12/3
a=-4
You will want to start by making your fractions have the same denominator. To do this, multiply the 2/3 by 2/2, to make it 4/6. Now we have this equation:
-4/6x = 1/6x + 4
Next, subtract 1/6x from both sides:
-5/6x = 4
Finally, multiply both sides by -6/5, and you get your answer:
x = -4.8
