Simplifying 4 + -2.5x(x + -6) = 3 + 7x Reorder the terms: 4 + -2.5x(-6 + x) = 3 + 7x 4 + (-6 * -2.5x + x * -2.5x) = 3 + 7x 4 + (15x + -2.5x2) = 3 + 7x Solving 4 + 15x + -2.5x2 = 3 + 7x Solving for variable 'x'. Reorder the terms: 4 + -3 + 15x + -7x + -2.5x2 = 3 + 7x + -3 + -7x Combine like terms: 4 + -3 = 1 1 + 15x + -7x + -2.5x2 = 3 + 7x + -3 + -7x Combine like terms: 15x + -7x = 8x 1 + 8x + -2.5x2 = 3 + 7x + -3 + -7x Reorder the terms: 1 + 8x + -2.5x2 = 3 + -3 + 7x + -7x Combine like terms: 3 + -3 = 0 1 + 8x + -2.5x2 = 0 + 7x + -7x 1 + 8x + -2.5x2 = 7x + -7x Combine like terms: 7x + -7x = 0 1 + 8x + -2.5x2 = 0 Begin completing the square. Divide all terms by -2.5 the coefficient of the squared term: Divide each side by '-2.5'. -0.4 + -3.2x + x2 = 0 Move the constant term to the right: Add '0.4' to each side of the equation. -0.4 + -3.2x + 0.4 + x2 = 0 + 0.4 Reorder the terms: -0.4 + 0.4 + -3.2x + x2 = 0 + 0.4 Combine like terms: -0.4 + 0.4 = 0.0 0.0 + -3.2x + x2 = 0 + 0.4 -3.2x + x2 = 0 + 0.4 Combine like terms: 0 + 0.4 = 0.4 -3.2x + x2 = 0.4 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 = 0.4 + 2.56 Reorder the terms: 2.56 + -3.2x + x2 = 0.4 + 2.56 Combine like terms: 0.4 + 2.56 = 2.96 2.56 + -3.2x + x2 = 2.96 Factor a perfect square on the left side: (x + -1.6)(x + -1.6) = 2.96 Calculate the square root of the right side: 1.720465053 Break this problem into two subproblems by setting (x + -1.6) equal to 1.720465053 and -1.720465053.Subproblem 1
x + -1.6 = 1.720465053 Simplifying x + -1.6 = 1.720465053 Reorder the terms: -1.6 + x = 1.720465053 Solving -1.6 + x = 1.720465053 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 = 1.720465053 + 1.6 Combine like terms: -1.6 + 1.6 = 0.0 0.0 + x = 1.720465053 + 1.6 x = 1.720465053 + 1.6 Combine like terms: 1.720465053 + 1.6 = 3.320465053 x = 3.320465053 Simplifying x = 3.320465053Subproblem 2
x + -1.6 = -1.720465053 Simplifying x + -1.6 = -1.720465053 Reorder the terms: -1.6 + x = -1.720465053 Solving -1.6 + x = -1.720465053 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 = -1.720465053 + 1.6 Combine like terms: -1.6 + 1.6 = 0.0 0.0 + x = -1.720465053 + 1.6 x = -1.720465053 + 1.6 Combine like terms: -1.720465053 + 1.6 = -0.120465053 x = -0.120465053 Simplifying x = -0.120465053Solution
The solution to the problem is based on the solutions from the subproblems. x = {3.320465053, -0.120465053}
