Simplifying 5x2 + -101x + -15 = 0 Reorder the terms: -15 + -101x + 5x2 = 0 Solving -15 + -101x + 5x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -3 + -20.2x + x2 = 0 Move the constant term to the right: Add '3' to each side of the equation. -3 + -20.2x + 3 + x2 = 0 + 3 Reorder the terms: -3 + 3 + -20.2x + x2 = 0 + 3 Combine like terms: -3 + 3 = 0 0 + -20.2x + x2 = 0 + 3 -20.2x + x2 = 0 + 3 Combine like terms: 0 + 3 = 3 -20.2x + x2 = 3 The x term is -20.2x. Take half its coefficient (-10.1). Square it (102.01) and add it to both sides. Add '102.01' to each side of the equation. -20.2x + 102.01 + x2 = 3 + 102.01 Reorder the terms: 102.01 + -20.2x + x2 = 3 + 102.01 Combine like terms: 3 + 102.01 = 105.01 102.01 + -20.2x + x2 = 105.01 Factor a perfect square on the left side: (x + -10.1)(x + -10.1) = 105.01 Calculate the square root of the right side: 10.247438704 Break this problem into two subproblems by setting (x + -10.1) equal to 10.247438704 and -10.247438704.Subproblem 1
x + -10.1 = 10.247438704 Simplifying x + -10.1 = 10.247438704 Reorder the terms: -10.1 + x = 10.247438704 Solving -10.1 + x = 10.247438704 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '10.1' to each side of the equation. -10.1 + 10.1 + x = 10.247438704 + 10.1 Combine like terms: -10.1 + 10.1 = 0.0 0.0 + x = 10.247438704 + 10.1 x = 10.247438704 + 10.1 Combine like terms: 10.247438704 + 10.1 = 20.347438704 x = 20.347438704 Simplifying x = 20.347438704Subproblem 2
x + -10.1 = -10.247438704 Simplifying x + -10.1 = -10.247438704 Reorder the terms: -10.1 + x = -10.247438704 Solving -10.1 + x = -10.247438704 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '10.1' to each side of the equation. -10.1 + 10.1 + x = -10.247438704 + 10.1 Combine like terms: -10.1 + 10.1 = 0.0 0.0 + x = -10.247438704 + 10.1 x = -10.247438704 + 10.1 Combine like terms: -10.247438704 + 10.1 = -0.147438704 x = -0.147438704 Simplifying x = -0.147438704Solution
The solution to the problem is based on the solutions from the subproblems. x = {20.347438704, -0.147438704}
