Since you are solving for a, you want to have a on one side of the equation and the other terms on another side of the equation. It would be easiest to have all the terms with a on the left side of the equation, so that is what we will do.
Subtract 9a from both sides to get a on the left side of the equation.
5 + 5a = -5
Subtract 5 from both sides of the equation to isolate the term with a.
5a = -10
Divide both sides of the equation by 5 to solve for a.
a = -2
Answer:

Answer:
x^3-2x^2-13x+6
Step-by-step explanation:
We are to simplify the expression (x+3)(x^2−5x+2). This is as shown;
(x+3)(x^2−5x+2)
Expand
= x(x^2)-5x(x)+2x+3x^2-3(5x)+6
= x^3 - 5x^2+2x+3x^2-15x+6
Collect the like terms
= x^3 - 5x^2+3x^2+2x-15x=6
= x^3-2x^2-13x+6
This gives the required expression
