Question 824044: I need mire detail solution (and explanation what formulas should be used):
The two straight lines y=3x+1 and y=-2x+16 and the curve y=x%5E2%2Bx-a, where a is a
constant, all meet at the same point. Find the value of a and then, for that value of a, plot the
curve y=x%5E2%2Bx-a. The turning point and the points where the curve meets the axes should be
clearly marked.

The two straight lines y=3x+1 and y=-2x+16 and the curve y=x%5E2%2Bx-a, where a is a
constant, all meet at the same point. Find the value of a and then, for that value of a, plot the
curve y=x%5E2%2Bx-a.
--------------------
Find the intersection of the 2 lines.
Solve for a.
Plot the curve.
