A = 3 b = -16 and c = 2
the radicand would be
sq root (b^2 -4*a*c) =
sq root (256 -4*3*2) =
sq root (232)
So the roots will be real and not complex.
The least common multiple of 18 and 42 is 126. Sorry I don't know how to explain it.
The answer is A. Here's the equation graphed and shows why the answer is A
The quotient is 5x+3 and the remainder is 5/x-1
