Question

Factorise and divide:- 15(y+3)(y^2 - 16) / 5(y^2-y-12)
result
multipled by 3(y+4)

Answer 1

Step-by-step explanation:

Factorising 15 (y + 3) (y2 – 16), we get 5 × 3 × (y + 3) (y – 4) (y + 4) On factorising 5 (y2 – y – 12), we get 5 (y2 – 4y + 3y – 12) = 5 [y (y – 4) + 3 (y – 4)] = 5 (y – 4) (y + 3) Therefore, on dividing the first expression by the second ← Prev QuestionNext Question → Read more on Sarthaks.com - https://www.sarthaks.com/852625/divide-15-y-3-y-2-16-by-5-y-2-y-12?show=852626#a852626
