Simplifying 5x(2x + -3) = 7x + 1 Reorder the terms: 5x(-3 + 2x) = 7x + 1 (-3 * 5x + 2x * 5x) = 7x + 1 (-15x + 10x2) = 7x + 1 Reorder the terms: -15x + 10x2 = 1 + 7x Solving -15x + 10x2 = 1 + 7x Solving for variable 'x'. Reorder the terms: -1 + -15x + -7x + 10x2 = 1 + 7x + -1 + -7x Combine like terms: -15x + -7x = -22x -1 + -22x + 10x2 = 1 + 7x + -1 + -7x Reorder the terms: -1 + -22x + 10x2 = 1 + -1 + 7x + -7x Combine like terms: 1 + -1 = 0 -1 + -22x + 10x2 = 0 + 7x + -7x -1 + -22x + 10x2 = 7x + -7x Combine like terms: 7x + -7x = 0 -1 + -22x + 10x2 = 0 Begin completing the square. Divide all terms by 10 the coefficient of the squared term: Divide each side by '10'. -0.1 + -2.2x + x2 = 0.0 Move the constant term to the right: Add '0.1' to each side of the equation. -0.1 + -2.2x + 0.1 + x2 = 0.0 + 0.1 Reorder the terms: -0.1 + 0.1 + -2.2x + x2 = 0.0 + 0.1 Combine like terms: -0.1 + 0.1 = 0.0 0.0 + -2.2x + x2 = 0.0 + 0.1 -2.2x + x2 = 0.0 + 0.1 Combine like terms: 0.0 + 0.1 = 0.1 -2.2x + x2 = 0.1 The x term is -2.2x. Take half its coefficient (-1.1). Square it (1.21) and add it to both sides. Add '1.21' to each side of the equation. -2.2x + 1.21 + x2 = 0.1 + 1.21 Reorder the terms: 1.21 + -2.2x + x2 = 0.1 + 1.21 Combine like terms: 0.1 + 1.21 = 1.31 1.21 + -2.2x + x2 = 1.31 Factor a perfect square on the left side: (x + -1.1)(x + -1.1) = 1.31 Calculate the square root of the right side: 1.144552314 Break this problem into two subproblems by setting (x + -1.1) equal to 1.144552314 and -1.144552314.Subproblem 1
x + -1.1 = 1.144552314 Simplifying x + -1.1 = 1.144552314 Reorder the terms: -1.1 + x = 1.144552314 Solving -1.1 + x = 1.144552314 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.1' to each side of the equation. -1.1 + 1.1 + x = 1.144552314 + 1.1 Combine like terms: -1.1 + 1.1 = 0.0 0.0 + x = 1.144552314 + 1.1 x = 1.144552314 + 1.1 Combine like terms: 1.144552314 + 1.1 = 2.244552314 x = 2.244552314 Simplifying x = 2.244552314Subproblem 2
x + -1.1 = -1.144552314 Simplifying x + -1.1 = -1.144552314 Reorder the terms: -1.1 + x = -1.144552314 Solving -1.1 + x = -1.144552314 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.1' to each side of the equation. -1.1 + 1.1 + x = -1.144552314 + 1.1 Combine like terms: -1.1 + 1.1 = 0.0 0.0 + x = -1.144552314 + 1.1 x = -1.144552314 + 1.1 Combine like terms: -1.144552314 + 1.1 = -0.044552314 x = -0.044552314 Simplifying x = -0.044552314Solution
The solution to the problem is based on the solutions from the subproblems. x = {2.244552314, -0.044552314}
