Question 548917: Hello, I need to know how to solve 43x^2-52x=14. I can get the quadratic equation just cant solve and get the 2 solution
also profit function, p(x)=2x^2+240x-6400
# of items produced and sold that maximize profit and the amount of profit
also when it breaks even profit =0
CaN YOU SHOW ME THE STEPS

I need to know how to solve 43x^2-52x=14.
I can get the quadratic equation just cant solve and get the 2 solution
---
43x^2-52x-14 = 0
x = [52+-sqrt(52^2-4*43*-14)]/86
------
x = [52 +-sqrt(5112)]/86
---
x = [52 +- 71.5]/86
===================================
also profit function, p(x)=2x^2+240x-6400
# of items produced and sold that maximize profit and the amount of profit
also when it breaks even profit =0
-----
That function has no maximum because the coefficient
of x^2 is positive.
