Question

factorise the following 4(x+3y)3+12(x+3y)2​

Answer 1

Answer:

((4•(x+3y))•3)+(12•(x+3y)•2)

((4 • (x + 3y)) • 3) + 24 • (x + 3y)

(4 • (x + 3y) • 3) + 24 • (x + 3y)

12 • (x + 3y) + 24 • (x + 3y)

5.1 Pull out x+3y

After pulling out, we are left with :

(x+3y) • ( 12 * 1 - 24 * (-1) ))

final result:36 • (x + 3y)
