-16 + 4(2g - 18) = 0
Distribute 4 inside the parentheses.
-16 + (8g - 72) = 0
Combine like terms (-16 - 72).
-88 + 8g = 0
Add 88 to both sides.
8g = 88
Divide both sides by 8.
Answer:
After completing the square the expression is (x-2)^2 -12 =0 and real solution are x = 5.46 and x = -1.46
Step-by-step explanation:
We need to complete the square:
x^2 − 4x − 8 = 0
x^2 -2(x)(2)+(2)^2 -8 -4 =0
(x^2 -4x +4) - 12 = 0
(x-2)^2 -12 =0
Now, finding the value of x
(x-2)^2 -12 =0
(x-2)^2 = 12
taking square root on both sides
So, After completing the square the expression is (x-2)^2 -12 =0 and real solution are x = 5.46 and x = -1.46
