Bob's skate shop had a profit of $3,563 during the month of august. the company models its profit using p=x^2+10x-12 where x is the number of skateboards the company sells. how many skateboards did the company sell during the month of august?

I entered the equation into a graphing calculator. clicked table and then scrolled down to the profit of $3,563. 55 skateboards
you could also try this equation. B=the number attached to x so 10, a=the number attached to x^2(or in other equation x^3 etc) so 1 and c is the number, so -12.
