WebNot all quadratic equations are solved by immediately taking the square root. Sometimes we have to isolate the squared term before taking its root. For example, to solve the equation … WebSolve: −200P 2 + 92,000P − 8,400,000 = 0. Step 1 Divide all terms by -200. P 2 – 460P + 42000 = 0. Step 2 Move the number term to the right side of the equation: P 2 – 460P = -42000. Step 3 Complete the square on the left side of the equation and balance this by adding the same number to the right side of the equation:
