Question

Pleaseeeeee help with math. i’ve gotten no help today. explantion needed!!

Answer 1

use what is in the parenthesis and make it equal zero. (x-1) means x is 1 because 1-1 is zero :)

Answer 2

Exactly two distinct zeros

Explanation:

y = 2(x-1) (x + 4)

Plug y = 0

0 = 2(x-1) (x + 4)

0/2 = (x-1) (x + 4)

(x-1) (x + 4) = 0

(x-1) = 0 or (x + 4)= 0

x = 1 or x = - 4

Here, x has two distinct roots, therefore given quadratic relation has Exactly two distinct zeros.
