Answer:
double, real root x = -4
Step-by-step explanation:
Please use " ^ " to indicate exponentation: 2х^2 + 8х = х^2 - 16.
Combine like terms:
х^2 + 8х = - 16.
Re-write in the standard form for a quadratic:
х^2 + 8х + 16 = 0
Recognize that this is the square of the binomial x + 4:
х^2 + 8х + 16 = 0 => (x + 4)^2 = 0
Solving this last result for x yields the double, real root x = -4.
Answer:
X = - 84
