Question

Find all the zeros of the quadratic function.

y=x^2+ 8x + 12

If there is more than one zero, separate them with commas.

If there are no zeros, click on "None".

Answer 1

x=-2, -6

Explanation:

factor the expression

y=x^2+ 8x + 12

y= (x+2)(x+6)

set the equation equal to 0, since you are finding zeros, or solutions

0=(x+2)(x+6)

split the equation into two parts

0=(x+2) and 0=(x+6)

solve the equations

you should get 2 zeros

x=-2, -6
