Simplifying (3x + 3)(x) = 77 Reorder the terms: (3 + 3x)(x) = 77 Reorder the terms for easier multiplication: x(3 + 3x) = 77 (3 * x + 3x * x) = 77 (3x + 3x2) = 77 Solving 3x + 3x2 = 77 Solving for variable 'x'. Reorder the terms: -77 + 3x + 3x2 = 77 + -77 Combine like terms: 77 + -77 = 0 -77 + 3x + 3x2 = 0 Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. -25.66666667 + x + x2 = 0 Move the constant term to the right: Add '25.66666667' to each side of the equation. -25.66666667 + x + 25.66666667 + x2 = 0 + 25.66666667 Reorder the terms: -25.66666667 + 25.66666667 + x + x2 = 0 + 25.66666667 Combine like terms: -25.66666667 + 25.66666667 = 0.00000000 0.00000000 + x + x2 = 0 + 25.66666667 x + x2 = 0 + 25.66666667 Combine like terms: 0 + 25.66666667 = 25.66666667 x + x2 = 25.66666667 The x term is x. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. + 0.25 + x2 = 25.66666667 + 0.25 Combine like terms: + 0.25 = 1.25 1.25 + x2 = 25.66666667 + 0.25 Combine like terms: 25.66666667 + 0.25 = 25.91666667 1.25 + x2 = 25.91666667 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = 25.91666667 Calculate the square root of the right side: 5.09084145 Break this problem into two subproblems by setting (x + 0.5) equal to 5.09084145 and -5.09084145.Subproblem 1
x + 0.5 = 5.09084145 Simplifying x + 0.5 = 5.09084145 Reorder the terms: 0.5 + x = 5.09084145 Solving 0.5 + x = 5.09084145 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = 5.09084145 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = 5.09084145 + -0.5 x = 5.09084145 + -0.5 Combine like terms: 5.09084145 + -0.5 = 4.59084145 x = 4.59084145 Simplifying x = 4.59084145Subproblem 2
x + 0.5 = -5.09084145 Simplifying x + 0.5 = -5.09084145 Reorder the terms: 0.5 + x = -5.09084145 Solving 0.5 + x = -5.09084145 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = -5.09084145 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = -5.09084145 + -0.5 x = -5.09084145 + -0.5 Combine like terms: -5.09084145 + -0.5 = -5.59084145 x = -5.59084145 Simplifying x = -5.59084145Solution
The solution to the problem is based on the solutions from the subproblems. x = {4.59084145, -5.59084145}
