Question

If the solutions to a quadratic equation are - 3 and + 4, what is the equation?

Be careful to write the quadratic in standard form: Ax2 + Bx + C = 0.

A, B, and C must be integers - no fractions, no decimals - and A must be positive.

The equation is

Answer 1

f(x) = x^2 - x - 12

Explanation:

The function is f(x) = (x + 3)(x - 4), or f(x) = x^2 - x - 12. Here, a = 1, b = -1, and c = -12.
