What is the factored form of the quadratic equation y=x2+4x-12? <br><br> PLEASE HELP ME!!!
snow_tiger [21]

Answer:

(x + 6)(x - 2)

Step-by-step explanation:

The given quadratic equation is $ y = x^2 + 4x - 12 $.

A quadratic equation can be factored in the form $ (x - a) (x - b) $ where $ -a $ and $ -b $ will form the roots of the equation

Here the roots are $ - 6 $ and $ 2 $.

The factored form would simply be: $ (x + 6) (x - 2) = 0 $.

Thus the answer.
