Question

Which of the binomials below is a factor of this trinomial x^2+13x+40

Answer 1

Answer:

The factor form of the given equation is $(x+8)(x+5)$. It means either (x+8) or (x+5) binomial is a factor of given trinomial.

Step-by-step explanation:

The given trinomial is

$x^2+13x+40$

We have to find the factor form of the given trinomial.

Written the middle term as 8x+5x.

$x^2+8x+5x+40$

$(x^2+8x)+(5x+40)$

Taking out common factors from each parenthesis.

$x(x+8)+5(x+8)$

Taking out common factors.

$(x+8)(x+5)$

The factor form of the given equation is $(x+8)(x+5)$. It means either (x+8) or (x+5) binomial is a factor of given trinomial.

Answer 2

Factor the equation:

x^2+13x+40

x^2+5x+8x+40

x(x+5)+8(x+5)

(x+5)(x+8)

Those are the two factors...
