Question

factorise 7+10(2x-3y)-8(2x-3y)^2

Answer 1

Let (2x - 3y) = a

=> 7+ 10a - 8a^2

=> - [ 8a^2 - 10a - 7]

=> - [ 8a^2 - 14a +4a - 7]

=> - [ 2a(4a - 7) + 1(4a-7)]

=> - [ (2a+1)(4a-7)]

=> - [ { 2(2x-3y) +1} { 4(2x-3y) - 7}]

=> - [ ( 4x - 6y +1) (8x - 12y - 7)]

=> - (4x-6y+1)(8x-12y-4)

=> ( 6y - 4x - 1)(8x-12y-4)

Answer 2

heyyy friend!!!!! here is ur solution!!!!!!!!


7+20x-30y-16x+24y*2

7+20x-16x+24y-30y×2

(7+4x-6y)×2

14+8x-12y//


its the answer



hope dis helpsssss
