Question

Divide the following by the method of factorisation. 66(y^4 – 5y^3 – 24y^2 ) ÷ 6y(y – 8)​

Answer 1

Answer:

Step-by-step explanation:

66(y⁴ - 5y³ - 24y²) / 6y(y-8)

// take y² common

=> 66y²(y² - 5y - 24) / 6y(y-8)

=> 66y²(y² - 8y + 3y - 24) / 6y(y-8)

=> 66y²[y(y-8) + 3(y-8)] / 6y(y-8)

=> 66y²(y-8)(y+3) / 6y(y-8)

=> 11y(y+3)
