Find the zeros of the function. y=1/2(2x+5)(x+4)

i think the answers are x=-2.5 and x=-4 but i'm not sure about the -2.5 pls

x = - 2.5, x = - 4

Step-by-step explanation:

To find the zeros, set y = 0, that is

(2x + 5)(x + 4) = 0

Equate each of the factors to zero and solve for x

2x + 5 = 0 ⇒ 2x = - 5 ⇒ x = - 2.5

x + 4 = 0 ⇒ x = - 4
