Question

The solutions to a certain quadratic equation are x= -4 and X = 3. Write the equation in standard form below.

[blank] +x [blank] [blank] = 0

Answer 1

x² + x - 12 = 0

Explanation:

If x = -4 and x = 3 are solutions to a quadratic equation, then

(x + 4)(x - 3) = 0

Expand the brackets: x² - 3x + 4x - 12 = 0

Combine like terms: x² + x - 12 = 0
