`15 {x}^(2) - 11x - 12`

Answer 1

Given:

The polynomial

`15x^2-11x-12`

Required:

Factor this polynomial completely.

Step-by-step explanation:

We will solve as:

`\begin{gathered} 15x^2-11x-12 \\ 15x^2-20x+9x-12 \\ 5x(3x-4)+3(3x-4) \\ (5x+3)(3x-4) \end{gathered}`

Answer:

Factor of polynomial is (5x + 3)(3x - 4).
