Simplifying 5x(3 + -1x) = 7 + -1x (3 * 5x + -1x * 5x) = 7 + -1x (15x + -5x2) = 7 + -1x Solving 15x + -5x2 = 7 + -1x Solving for variable 'x'. Reorder the terms: -7 + 15x + x + -5x2 = 7 + -1x + -7 + x Combine like terms: 15x + x = 16x -7 + 16x + -5x2 = 7 + -1x + -7 + x Reorder the terms: -7 + 16x + -5x2 = 7 + -7 + -1x + x Combine like terms: 7 + -7 = 0 -7 + 16x + -5x2 = 0 + -1x + x -7 + 16x + -5x2 = -1x + x Combine like terms: -1x + x = 0 -7 + 16x + -5x2 = 0 Begin completing the square. Divide all terms by -5 the coefficient of the squared term: Divide each side by '-5'. 1.4 + -3.2x + x2 = 0 Move the constant term to the right: Add '-1.4' to each side of the equation. 1.4 + -3.2x + -1.4 + x2 = 0 + -1.4 Reorder the terms: 1.4 + -1.4 + -3.2x + x2 = 0 + -1.4 Combine like terms: 1.4 + -1.4 = 0.0 0.0 + -3.2x + x2 = 0 + -1.4 -3.2x + x2 = 0 + -1.4 Combine like terms: 0 + -1.4 = -1.4 -3.2x + x2 = -1.4 The x term is -3.2x. Take half its coefficient (-1.6). Square it (2.56) and add it to both sides. Add '2.56' to each side of the equation. -3.2x + 2.56 + x2 = -1.4 + 2.56 Reorder the terms: 2.56 + -3.2x + x2 = -1.4 + 2.56 Combine like terms: -1.4 + 2.56 = 1.16 2.56 + -3.2x + x2 = 1.16 Factor a perfect square on the left side: (x + -1.6)(x + -1.6) = 1.16 Calculate the square root of the right side: 1.077032961 Break this problem into two subproblems by setting (x + -1.6) equal to 1.077032961 and -1.077032961.Subproblem 1
x + -1.6 = 1.077032961 Simplifying x + -1.6 = 1.077032961 Reorder the terms: -1.6 + x = 1.077032961 Solving -1.6 + x = 1.077032961 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.6' to each side of the equation. -1.6 + 1.6 + x = 1.077032961 + 1.6 Combine like terms: -1.6 + 1.6 = 0.0 0.0 + x = 1.077032961 + 1.6 x = 1.077032961 + 1.6 Combine like terms: 1.077032961 + 1.6 = 2.677032961 x = 2.677032961 Simplifying x = 2.677032961Subproblem 2
x + -1.6 = -1.077032961 Simplifying x + -1.6 = -1.077032961 Reorder the terms: -1.6 + x = -1.077032961 Solving -1.6 + x = -1.077032961 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.6' to each side of the equation. -1.6 + 1.6 + x = -1.077032961 + 1.6 Combine like terms: -1.6 + 1.6 = 0.0 0.0 + x = -1.077032961 + 1.6 x = -1.077032961 + 1.6 Combine like terms: -1.077032961 + 1.6 = 0.522967039 x = 0.522967039 Simplifying x = 0.522967039Solution
The solution to the problem is based on the solutions from the subproblems. x = {2.677032961, 0.522967039}
