Hello, my fellow math friends. I am here, yet again, because I fail at life. And Algebra. Help me plz.
Use the quadratic formula to solve the equation:
0 = x^2 + x - 20
Use the quadratic formula to solve the equation:
0 = x^2 - 5x + 6
Decide how many solutions this equation has:
x^2 - 2x + 1 = 0
Decide how many solutions this equation has:
x^2 + 3 = 0
The revenue from selling (x) units of a product is given by y = -0.0002x^2 + 20x. How many units must be sold in order to have the greatest revenue? (Find the x-coordinate of the vertex of the parabola.)
