Simplifying 5x2 + -3x = 142 Reorder the terms: -3x + 5x2 = 142 Solving -3x + 5x2 = 142 Solving for variable 'x'. Reorder the terms: -142 + -3x + 5x2 = 142 + -142 Combine like terms: 142 + -142 = 0 -142 + -3x + 5x2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -28.4 + -0.6x + x2 = 0 Move the constant term to the right: Add '28.4' to each side of the equation. -28.4 + -0.6x + 28.4 + x2 = 0 + 28.4 Reorder the terms: -28.4 + 28.4 + -0.6x + x2 = 0 + 28.4 Combine like terms: -28.4 + 28.4 = 0.0 0.0 + -0.6x + x2 = 0 + 28.4 -0.6x + x2 = 0 + 28.4 Combine like terms: 0 + 28.4 = 28.4 -0.6x + x2 = 28.4 The x term is -0.6x. Take half its coefficient (-0.3). Square it (0.09) and add it to both sides. Add '0.09' to each side of the equation. -0.6x + 0.09 + x2 = 28.4 + 0.09 Reorder the terms: 0.09 + -0.6x + x2 = 28.4 + 0.09 Combine like terms: 28.4 + 0.09 = 28.49 0.09 + -0.6x + x2 = 28.49 Factor a perfect square on the left side: (x + -0.3)(x + -0.3) = 28.49 Calculate the square root of the right side: 5.337602458 Break this problem into two subproblems by setting (x + -0.3) equal to 5.337602458 and -5.337602458.Subproblem 1
x + -0.3 = 5.337602458 Simplifying x + -0.3 = 5.337602458 Reorder the terms: -0.3 + x = 5.337602458 Solving -0.3 + x = 5.337602458 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.3' to each side of the equation. -0.3 + 0.3 + x = 5.337602458 + 0.3 Combine like terms: -0.3 + 0.3 = 0.0 0.0 + x = 5.337602458 + 0.3 x = 5.337602458 + 0.3 Combine like terms: 5.337602458 + 0.3 = 5.637602458 x = 5.637602458 Simplifying x = 5.637602458Subproblem 2
x + -0.3 = -5.337602458 Simplifying x + -0.3 = -5.337602458 Reorder the terms: -0.3 + x = -5.337602458 Solving -0.3 + x = -5.337602458 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.3' to each side of the equation. -0.3 + 0.3 + x = -5.337602458 + 0.3 Combine like terms: -0.3 + 0.3 = 0.0 0.0 + x = -5.337602458 + 0.3 x = -5.337602458 + 0.3 Combine like terms: -5.337602458 + 0.3 = -5.037602458 x = -5.037602458 Simplifying x = -5.037602458Solution
