What percentage of the population was opposed to building both the swimming pool and the soccer complex? (Hint: This is not the same as the percentage of the population who support neither the swimming pool nor the soccer field. That percentage of the population is opposed to either the swimming pool or the soccer complex or both. Here we’re looking for the percentage of the population opposed to both. Use your knowledge of complementary events to find the answer.)

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629

what are the answer choices given for this problem?

answer: a parabola

steps:

(x-1)(x+4)   = x(x+4) - 1(x+4) = (x^2 + 4x) - (x+4)

                = x^2 +4x -x -4   = x^2 +3x -4

which is a parabola
