Question

36y^2-84y-147 factor

Answer 1

First of all u can factor this as -

3(12y^2-28y-49)

-49x12 = -588.

and even -42 x 14 = -588.

=> 3 (12^y2 - 42 y + 14 y - 49)

solve accordingly :)

Answer 2

36y^2-84y-147
={(6y)^2-2*6y*7+7^2-7^2}-147
=(6y-7)^2-49-147
=(6y-7)^2-196
=(6y-7)^2-14^2
=(6y-7+14)(6y-7-21)
=(6y+7)(6y-21)

Answer 3

=(6y+7)3(2y-7)
=3(6y+7)(2y-7)
