Question

One x-intercept for a parabola is at the point (-3,0). Use the factor method to find the other x-intercept for the parabola defined by the equation y=-x^2-5x-6

Answer 1

for a given root (r), a factor can be produced as (x-r)

(x-r) (ax + b) = -x^2 -5x -6

expand the left side and compare parts ....
