Explanation:

The given equation is:

[tex]\begin{gathered} 5a^2+55a-90 \\ 5(a^2+11a-18) \end{gathered}[/tex]

To factorize, we will use the following equation:

[tex]a=\frac{-c_2_{}\pm\sqrt[]{(c_2)^2-4(c_1)(c_3)}}{2(c_1)}[/tex]

Where c1 is the number besides a², c2 is the number beside a, and c3 is the constant.

Replacing c1 = 1, c2 = 11, and c3 = -18, we get:
