ANSWER
EXPLANATION
The given isosceles tra-pezoid has legs
and
The base is bc=5y+2.
The length of the legs of the isosceles tra-pezoid are equal.
This implies that,
Thus,
Group similar terms,
Divide both sides by 9.
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.
