Question

factorise 6 x square- x- 15​

Answer 1

Answer:

The answer is $(2x+3)(3x-5)$

Step-by-step explanation:

Given expression      

    $=6x^2-x-15$

Split the middle term  

    $=6x^2+9x-10x-15$

Group the terms

    $=(6x^2+9x)+(-10x-15)$

Factor both terms  

    $=3x(2x+3)-5(2x+3)$

Factor out common term

     $=(2x+3)(3x-5)$
