Yes that’s correct i did this before
Answer:
(-8 , 0)
(10 , 0)
Step-by-step explanation:
(-8)^2 - 2(-8) - 80 = 0
(10)^2 - 2(10) - 80 = 0
then (-8 , 0) and (10 , 0) are x-intercepts Of the polynomial f
the others are not because (for instance):
(8)^2-2(8)-80 =
:)-32
The product is
(-d)^2 -4^2 = d^2 -16 . . . . . corresponds to the 2nd selection
Solve : 9x-14 = 0
Add 14 to both sides of the equation
9x = 14
Divide both sides of the equation by 9:
x = 14/9
