i need to know how to find the intercept , find the vertex and graph it in t chart form every time i do the chart it doesnt look right
the problem is y=2(x+4)(x+2)
Answer by Earlsdon(6294) (Show Source): You can put this solution on YOUR website!
To find the x-intercepts, set y equal to zero.
so...
, therefore, the x-intercepts are...
and
The x-coordinate of the vertex is found by:
Expand the given equation by multiplying the factors:

so a = 2 and b = 12, then,
= Substitute into the original equation to find the y-coordinate.

The vertex is at (-3, -2)
