Answer:
x=0,1,-1
Step-by-step explanation:
It factors as
X(x+1)(x-1)=0
Simplify
7x^2 - 2x + 19 + 2x^2 - 7x + 4
Collect like terms;
(7x^2 + 2x^2) + (-2x - 7x) + (19 + 4)
Simplify
<u>9x^2 - 9x + 23</u>
A.)The equation is 24 + 8=32. Twice of the amount of 24 is 6 times the amount of 8. 24 x 2= 48. 48/6=8.
