Question

The binomial (x + 5) is a factor of x2 + 8x + 15. What is the other factor? (x + 3) (x + 7) (x + 12) (x + 13)

Answer 1

Answer: $x+3$

Step-by-step explanation:

Given

$(x+5)$ is a factor of $x^2+8x+15$ , that is

If $x^2+8x+15$ is divided by $(x+5)$, it yields 0 remainder

Solve the quadratic equation

$\Rightarrow x^2+8x+15=0\\\Rightarrow x^2+3x+5x+15=0\\\Rightarrow (x+3)(x+5)=0\\\Rightarrow x=-3,-5$

Therefore, $x+3$ is another factor of the quadratic equation.
