$8000+60x^2-80=0$
Learn how to solve problems step by step online. Solve the equation 20^3+60x^2+-80=0. Calculate the power 20^3. Subtract the values 8000 and -80. We need to isolate the dependent variable , we can do that by simultaneously subtracting 7920 from both sides of the equation. Canceling terms on both sides.
