Simplifying 5x2 + -13 = -9x Reorder the terms: -13 + 5x2 = -9x Solving -13 + 5x2 = -9x Solving for variable 'x'. Reorder the terms: -13 + 9x + 5x2 = -9x + 9x Combine like terms: -9x + 9x = 0 -13 + 9x + 5x2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -2.6 + 1.8x + x2 = 0 Move the constant term to the right: Add '2.6' to each side of the equation. -2.6 + 1.8x + 2.6 + x2 = 0 + 2.6 Reorder the terms: -2.6 + 2.6 + 1.8x + x2 = 0 + 2.6 Combine like terms: -2.6 + 2.6 = 0.0 0.0 + 1.8x + x2 = 0 + 2.6 1.8x + x2 = 0 + 2.6 Combine like terms: 0 + 2.6 = 2.6 1.8x + x2 = 2.6 The x term is 1.8x. Take half its coefficient (0.9). Square it (0.81) and add it to both sides. Add '0.81' to each side of the equation. 1.8x + 0.81 + x2 = 2.6 + 0.81 Reorder the terms: 0.81 + 1.8x + x2 = 2.6 + 0.81 Combine like terms: 2.6 + 0.81 = 3.41 0.81 + 1.8x + x2 = 3.41 Factor a perfect square on the left side: (x + 0.9)(x + 0.9) = 3.41 Calculate the square root of the right side: 1.846618531 Break this problem into two subproblems by setting (x + 0.9) equal to 1.846618531 and -1.846618531.Subproblem 1
x + 0.9 = 1.846618531 Simplifying x + 0.9 = 1.846618531 Reorder the terms: 0.9 + x = 1.846618531 Solving 0.9 + x = 1.846618531 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.9' to each side of the equation. 0.9 + -0.9 + x = 1.846618531 + -0.9 Combine like terms: 0.9 + -0.9 = 0.0 0.0 + x = 1.846618531 + -0.9 x = 1.846618531 + -0.9 Combine like terms: 1.846618531 + -0.9 = 0.946618531 x = 0.946618531 Simplifying x = 0.946618531Subproblem 2
x + 0.9 = -1.846618531 Simplifying x + 0.9 = -1.846618531 Reorder the terms: 0.9 + x = -1.846618531 Solving 0.9 + x = -1.846618531 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.9' to each side of the equation. 0.9 + -0.9 + x = -1.846618531 + -0.9 Combine like terms: 0.9 + -0.9 = 0.0 0.0 + x = -1.846618531 + -0.9 x = -1.846618531 + -0.9 Combine like terms: -1.846618531 + -0.9 = -2.746618531 x = -2.746618531 Simplifying x = -2.746618531Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.946618531, -2.746618531}
