Factor 36x^2 + 11x-12 please hurry​
xz_007 [3.2K]

Answer:

The answer is

<h2>(9x - 4)(4x + 3)</h2>

Step-by-step explanation:

36x² + 11x - 12

To factor the expression rewrite 11x as a difference

That's

36x² + 27x - 16x - 12

<u>Factor out 9x from the expression</u>

9x( 4x + 3) - 16x - 12

<u>Factor out - 4 from the expression</u>

9x( 4x + 3) - 4( 4x + 3)

Factor out 4x + 3 from the expression

We have the final answer as

<h3>(9x - 4)(4x + 3)</h3>

Hope this helps you
