Question

factories: a)16a²-24ab b)6a(a-2b)+5b(a-2b) c)(x+5)²-4(x+5) d)(x+y) (2x+5) - (x+y) (x+3)
With the solution


​

Answer 1

a) 16a²-24ab = 8a(2a-3b)

b)6a(a-2b)+5b(a-2b) = (6a+5b)(a-2b)

c)(x+5)²-4(x+5) = (x+5)(x+5)-(4)(x+5) = (x+5-4)(x+5) = (x+1)(x+5)

d)(x+y)(2x+5)-(x+y)(x+3) = (x+y)(2x+5-(x+3)) = (x+y)(x+2)
