One x-intercept for a parabola is at the point
(-4,0). Use the factor method to find the other
x-intercept for the parabola defined by this
equation:
y=x2 + 6x + 8
Separate the values with a comma.

Respuesta :

Answer:

(-2,0)

Step-by-step explanation:

y=x^2+6x+8

(x+4)(x+2)

Answer:

Step-by-step explanation:

to find the x-intercepts put y=0

x²+6x+8=0

x²+4x+2x+8=0

x(x+4)+2(x+4)=0

(x+4)(x+2)=0

x=-4,-2

so x - intercepts are (-4,0) and (-2,0)
