Question

factorise the following expression 6y²+9y-6​

Answer 1

Answer:

$6 {y}^{2} + 9y - 6 \\ \\ = 3(2 {y}^{2} + 3y - 2) \\ \\ = 2 {y}^{2} + 3y - 2 \\ \\ = 2 {y}^{2} + (4 - 1)y - 2 \\ \\ = 2 {y}^{2} + 4y - y - 2 \\ \\ = 2y(y + 2) - 1(y + 2) \\ \\ = (2y - 1)(y + 2)$

Answer 2

Answer:

6y^2+(12-3)y-6

=6y^2+12y-3y-6

=6y(y+2)-3(y+2)

=3(y+2)(2y-1) is the correct answer.
