Question

${6x}^{2} + 9x - 15$
factorise​

Answer 1

Answer:

(x-1) (2x+5)

Step-by-step explanation:

6x² +9x -15= 0

=3(2x² +3x -5) = 0

=2x² +3x -5 = 0/3

=2x² +5x -2x -5 = 0

=x(2x +5) -1(2x +5)=0

=(x-1)(2x+5) =0

here is your answer

Answer 2

Step-by-step explanation:

$6 {x}^{2} + 9x - 15$

$6 {x}^{2} + 6x - 15x - 15$

$6x(x + 1) - 15(x + 1)$

$(6x - 15) \: (x + 1)$
