Question

Simplify the expressions.

A) (a b2)(a3 b) / (a2 b3)

B) (21 x5) / (3 x4)

C) (6 x4)(4 y2) / [ (3 x2)(16 y) ]

D) (4x - 12) / 4

E) (-5x - 10) / (x + 2)

F) (x2 - 4x - 12) / (x2 – 2x – 24)

Answer 1

A) (a b2) (a3 b)/ (a2 b3)= (a4 b3) / (a2 b3)=a2
B) (21×5)/(3×4)=35/4
C) (6×4)(4 y2)/[(3×2)(16 y)]=y
D) (4x-12)/4=(x-4)
E) (-5x-10)/(x+2)=(-5)
F) (x2-4x-12)/(x2-2x-24)=[(x+2)(x-6)] / [(x+4)(x-6)]=(x+2)/(x+4)
