find the x-intercepts??
Let y=0 and solve for x.
0=(x___)(x___) the blank gets filled with two numbers that multiply to get 8 and add to get 6. 2*4=8 and 2+4=6
0=(x+2)(x+4) Let each parentheses=0
x+2=0 and x+4=0
x=-2 and x=-4
The x-intercepts are (-2,0) and (-4,0)
This has no x-intercepts. It's not factorable. If you're familiar with the discriminant:
, you can tell if a quadratic equation has no x-intercepts if the discriminant is negative.
There are no x-intercepts.
