factorise 8xsquare-6x-9
KAS11:
8x2-6x-9
steps
i m writing plz wait
here we can split 6x
ie. 2x * 3x
so we will get (8x²-2x) ( 3x-9)
or it can be 8x² +12x-6x -9
4x ( 2x+3) - 3 ( 2x+3)
Ans :- (4x-3)(2x+3)
Yes its correct

8x² -6x -9
=8x² -12x +6x -9
=4x(2x -3 ) +3(2x -3)
=(4x +3) (2x -3)
hence, (4x +3) and(2x -3) are factors
=8x² -12x +6x -9
=4x(2x -3 ) +3(2x -3)
=(4x +3) (2x -3)
hence, (4x +3) and(2x -3) are factors

= 8x^2 - 6x - 9
= 8x^2 - 12x + 6x - 9
= 4x(2x-3) + 3(2x-3)
= (4x+3) (2x-3)
