Answer:

(2x+3)(2x-3)

Step-by-step explanation:Since you asked this question, I am going to assume you are not familiar with middle term factorisation.

I will explain the process as we continue.

Factorise (-6x^{2}-15x-9)

Multiply the coefficent of the variable on the leftmost side and the number on the rightmost side.i.e. 6*9=54.Dont consider positive or negative.

Next,Breakdown 54 into factors, and arrange them in such a way so that they form 15.i.e 54=2*3*3*3.

9+6=15

Rearranging them, we can write the equation as -

-6x^{2}-(9+6)x-9

-6x^{2}-9x-6x-9

Taking -3x common from first two values and -3 common from last two values we get= -3x(2x+3)-3(2x+3).

Therefore multiplying them,we get (2x+3)(-3x-3) which is the answer.

Hope this helps you. Please mark me as brainliest.

Thanks
