Question

one x-intercept for a parabola is at the point (-4, 0).use the factory method to find the other x-intercept for the parabola defined by this equation:Y=X*X+6x+8 separate the values with a comma

Answer 1

The x-intercepts occur when y=0.

0=2x2+8x−10

0=2(x2+4x−5)

0=x2+4x−5

0=(x+5)(x−1)

x=−5 AND 1

Hence, the x intercepts are at (−5,0) and (1,0).

Hopefully this helps!

 

I hope I helped you. I do not speak English very well and I think the answer is right.
