Answer:
x - intercepts are (-7,0) and (-2,0)
A is the correct option.
Step-by-step explanation:
We have been given the equation of the parabola
For x- intercept, y = 0
We can split the middle term as 9x = 7x +2x
Now take GCF
Factored out the common term
Apply the zero product property
Solve for x
Hence, x - intercepts are (-7,0) and (-2,0)
A is the correct option.
