Solve: x^2 - 8x = 48. A. x = 68 B. x = -12 or -4 C. x = -4 ± 4√3 D. x = -4 or 12
D. x = -4 or 12
rewrite the equation as \[x^2 - 8x - 48 = 0\] now you have a quadratic that can be solved by factoring. find the factors of -48 that add to -8 the larger factor is negative. then you'll be able to find the solutions.
there you go, why worry about understanding when people just give answers
