Question

Workout the following divisions:

i) 36(x + 4)(x² + 7x + 10) ÷ 9(x + 4)

ii) a(a+1)(a+2)(a + 3) ÷ a(a + 3)

Answer 1

i) 36(x + 4)(x² + 7x + 10) ÷ 9(x + 4)

= 4( x² + 7x + 10) 

= 4( x² + 5x + 2x + 10) 

= 4[x( x + 5) +2(x + 5)] 

= 4( x + 5) (x + 2)

ii) a(a+1)(a+2)(a + 3) ÷ a(a + 3)

= ( a + 1)(a + 2)
