x = 7/2, x = -6

x = -5/2, x = 5

x = -3/7, x = 6

x = -5/2, x = 7

x = (5 - i√15)/2, (5 + i√15)/2

x = (5 - √15)/2, (5 + √15)/2

x = (5 - i√65)/2, (5 + i√65)/2

x = (5 - √65)/2, (5 + √65)/2

No real solution

Because zero is an easy number to work with.

Because we are trying to find the x-intercepts and that happens when y = 0.

Because setting it equal to zero helps us find the y-intercepts.

None of the above
