Answer:
z is equal to 0,4, and -3
Step-by-step explanation:
I don’t have the time for my birthday but I’m just asking for a little
(2x² - 8x - 10) ÷ 2 = 0
x² - 4x - 5 = 0
x² + x - 5x - 5 = 0
x(x+1) - 5(x+1) = 0
(x+1)(x-5) = 0
x+1 = 0 or x-5 = 0
x = -1 or x= 5
S = {-1;5}
The second one, fourth one, and sixth one are true.
Hope this helps!
