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
Step-by-step explanation:
y=(x+2) (-x-1)
(45) - (+14)
y= (x+2) (-x-1)
y=-2
