Simplifying 5x2 + 11x = 7(x + 3) Reorder the terms: 11x + 5x2 = 7(x + 3) Reorder the terms: 11x + 5x2 = 7(3 + x) 11x + 5x2 = (3 * 7 + x * 7) 11x + 5x2 = (21 + 7x) Solving 11x + 5x2 = 21 + 7x Solving for variable 'x'. Reorder the terms: -21 + 11x + -7x + 5x2 = 21 + 7x + -21 + -7x Combine like terms: 11x + -7x = 4x -21 + 4x + 5x2 = 21 + 7x + -21 + -7x Reorder the terms: -21 + 4x + 5x2 = 21 + -21 + 7x + -7x Combine like terms: 21 + -21 = 0 -21 + 4x + 5x2 = 0 + 7x + -7x -21 + 4x + 5x2 = 7x + -7x Combine like terms: 7x + -7x = 0 -21 + 4x + 5x2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -4.2 + 0.8x + x2 = 0 Move the constant term to the right: Add '4.2' to each side of the equation. -4.2 + 0.8x + 4.2 + x2 = 0 + 4.2 Reorder the terms: -4.2 + 4.2 + 0.8x + x2 = 0 + 4.2 Combine like terms: -4.2 + 4.2 = 0.0 0.0 + 0.8x + x2 = 0 + 4.2 0.8x + x2 = 0 + 4.2 Combine like terms: 0 + 4.2 = 4.2 0.8x + x2 = 4.2 The x term is 0.8x. Take half its coefficient (0.4). Square it (0.16) and add it to both sides. Add '0.16' to each side of the equation. 0.8x + 0.16 + x2 = 4.2 + 0.16 Reorder the terms: 0.16 + 0.8x + x2 = 4.2 + 0.16 Combine like terms: 4.2 + 0.16 = 4.36 0.16 + 0.8x + x2 = 4.36 Factor a perfect square on the left side: (x + 0.4)(x + 0.4) = 4.36 Calculate the square root of the right side: 2.088061302 Break this problem into two subproblems by setting (x + 0.4) equal to 2.088061302 and -2.088061302.Subproblem 1
x + 0.4 = 2.088061302 Simplifying x + 0.4 = 2.088061302 Reorder the terms: 0.4 + x = 2.088061302 Solving 0.4 + x = 2.088061302 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.4' to each side of the equation. 0.4 + -0.4 + x = 2.088061302 + -0.4 Combine like terms: 0.4 + -0.4 = 0.0 0.0 + x = 2.088061302 + -0.4 x = 2.088061302 + -0.4 Combine like terms: 2.088061302 + -0.4 = 1.688061302 x = 1.688061302 Simplifying x = 1.688061302Subproblem 2
x + 0.4 = -2.088061302 Simplifying x + 0.4 = -2.088061302 Reorder the terms: 0.4 + x = -2.088061302 Solving 0.4 + x = -2.088061302 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.4' to each side of the equation. 0.4 + -0.4 + x = -2.088061302 + -0.4 Combine like terms: 0.4 + -0.4 = 0.0 0.0 + x = -2.088061302 + -0.4 x = -2.088061302 + -0.4 Combine like terms: -2.088061302 + -0.4 = -2.488061302 x = -2.488061302 Simplifying x = -2.488061302Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.688061302, -2.488061302}
