Question

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

_+x_ _=0

Answer 1

If we had a quadratic function and solved for y when x are -4 and -3, the value of y would be zero.

 

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

 

 

Expand the right side of the function.

 

y = x² + x - 12

 

0 = x² + x - 12
