Simplifying (2x + 3)(x + 5) = 5 Reorder the terms: (3 + 2x)(x + 5) = 5 Reorder the terms: (3 + 2x)(5 + x) = 5 Multiply (3 + 2x) * (5 + x) (3(5 + x) + 2x * (5 + x)) = 5 ((5 * 3 + x * 3) + 2x * (5 + x)) = 5 ((15 + 3x) + 2x * (5 + x)) = 5 (15 + 3x + (5 * 2x + x * 2x)) = 5 (15 + 3x + (10x + 2x2)) = 5 Combine like terms: 3x + 10x = 13x (15 + 13x + 2x2) = 5 Solving 15 + 13x + 2x2 = 5 Solving for variable 'x'. Reorder the terms: 15 + -5 + 13x + 2x2 = 5 + -5 Combine like terms: 15 + -5 = 10 10 + 13x + 2x2 = 5 + -5 Combine like terms: 5 + -5 = 0 10 + 13x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 5 + 6.5x + x2 = 0 Move the constant term to the right: Add '-5' to each side of the equation. 5 + 6.5x + -5 + x2 = 0 + -5 Reorder the terms: 5 + -5 + 6.5x + x2 = 0 + -5 Combine like terms: 5 + -5 = 0 0 + 6.5x + x2 = 0 + -5 6.5x + x2 = 0 + -5 Combine like terms: 0 + -5 = -5 6.5x + x2 = -5 The x term is 6.5x. Take half its coefficient (3.25). Square it (10.5625) and add it to both sides. Add '10.5625' to each side of the equation. 6.5x + 10.5625 + x2 = -5 + 10.5625 Reorder the terms: 10.5625 + 6.5x + x2 = -5 + 10.5625 Combine like terms: -5 + 10.5625 = 5.5625 10.5625 + 6.5x + x2 = 5.5625 Factor a perfect square on the left side: (x + 3.25)(x + 3.25) = 5.5625 Calculate the square root of the right side: 2.358495283 Break this problem into two subproblems by setting (x + 3.25) equal to 2.358495283 and -2.358495283.Subproblem 1
x + 3.25 = 2.358495283 Simplifying x + 3.25 = 2.358495283 Reorder the terms: 3.25 + x = 2.358495283 Solving 3.25 + x = 2.358495283 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.25' to each side of the equation. 3.25 + -3.25 + x = 2.358495283 + -3.25 Combine like terms: 3.25 + -3.25 = 0.00 0.00 + x = 2.358495283 + -3.25 x = 2.358495283 + -3.25 Combine like terms: 2.358495283 + -3.25 = -0.891504717 x = -0.891504717 Simplifying x = -0.891504717Subproblem 2
x + 3.25 = -2.358495283 Simplifying x + 3.25 = -2.358495283 Reorder the terms: 3.25 + x = -2.358495283 Solving 3.25 + x = -2.358495283 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.25' to each side of the equation. 3.25 + -3.25 + x = -2.358495283 + -3.25 Combine like terms: 3.25 + -3.25 = 0.00 0.00 + x = -2.358495283 + -3.25 x = -2.358495283 + -3.25 Combine like terms: -2.358495283 + -3.25 = -5.608495283 x = -5.608495283 Simplifying x = -5.608495283Solution
