Question 5

To use the quadratic formula, we need to rewrite the equation so that all the terms are on one side: by subtracting (x+13) from both sides, we get that . The quadratic formula tells us that the roots of this are , where a=1, b=-1, and c=-6. This is equal to , which gives us the two roots -2 and 3.

Question 7

If you look at the attached graph, you will see that the graph of x^2-x-6 intersects the x-axis at the points (-2,0) and (3,0).

Question 8

The roots are the same. Both finding the x-intercepts and solving for the roots of a quadratic using the quadratic formula will give the values of x for which the function value is zero.
