Question

factorise 4x2+20x-96​

Answer 1

here is your answer

Answer 2

Answer:

4(x²+8)(x-3)

Step-by-step explanation:

we notice that 4 is common factor of all the terms.

Thus, 4x² +20x-96  =   4 ( x² + 5x -24 )

Now consider x² + 5x - 24

= x² + 8x - 3x - 24

=x ( x + 8 ) -3 ( x + 8 )

= ( x + 8 ) ( x - 3 )
