WebbSolve: −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: WebbSo applying the quadratic formula right here, we get our solutions to be x is equal to negative b. b is 10. So negative b is negative 10 plus or minus the square root of b squared. b is 10. So b squared is 100 minus 4 times a times c. So minus 4 times negative 3 times negative 3. Let me just write it down. charlie\u0027s hair shop
