Given:

The function is:


x^2-7x-18

Find-:

The binomials below are a factor of this trinomial

Explanation-:

Function is:


=x^2-7x-18

Factor is:


\begin{gathered} =x^2-7x-18 \\ \\ =x^2-9x+2x-18 \\ \\ \end{gathered}

The factor of quadratic equation,


\begin{gathered} =x^2-9x+2x-18 \\ \\ =x(x-9)+2(x-9) \\ \\ =(x-9)(x+2) \end{gathered}

The factore of this trinomial is x + 2.
