Answer:

x = - 2, x = - 1

Step-by-step explanation:

Given

y = (x + 2)(- x - 1)

To solve for x let y = 0, that is

(x + 2)(- x - 1) = 0

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

- x - 1 = 0 ⇒ - x = 1 ⇒ x = - 1

Answer:

(y^2+3y-28)/(4y^2-15y-4)

Step-by-step explanation:

(4y-1)(y-3)(2y+3)(y+3)(y+7)(y-3)/(2y+3)(y-4)(4y+1)(4y-1)(y-3)(y+3)

= (y+7)(y-3)/(y-4)(4y+1)

= (y^2+3y-28)/(4y^2-15y-4)
