Answer 1

Answer:

(y + 2)(y - 5)(y² - 3y + 5)

Step-by-step explanation:

Let y² - 3y = x,

=> (y² - 3y)² - 5(y² - 3y) - 50

=> x² - 5x - 50

=> x² - (10 - 5)x - 50

=> x² - 10x + 5x - 50

=> x(x - 10) + 5(x - 10)

=> (x - 10)(x + 5)

From above, x = y² - 3y,

=> (y² - 3y - 10)(y² - 3y + 5)

=> {y² - 5y + 2y - 10}(y² - 3y + 5)

=> {y(y - 5) + 2(y - 5)} (y² - 3y + 5)

=> (y + 2)(y - 5)(y² - 3y + 5)
