Question 81337
Hello there,

x = 3/7 and x = -3 is correct.

You actually could have solved this question more easily, by factoring the quadratic:

(7x - 3)(x + 3)

Now you can see that x MUST be x = 3/7 and x = - 3.

Also, you could have graphed this quadratic with your calculator to see if your x  -intercepts are right.
