Simplifying (2x + -7)(x + 3) = 4 Reorder the terms: (-7 + 2x)(x + 3) = 4 Reorder the terms: (-7 + 2x)(3 + x) = 4 Multiply (-7 + 2x) * (3 + x) (-7(3 + x) + 2x * (3 + x)) = 4 ((3 * -7 + x * -7) + 2x * (3 + x)) = 4 ((-21 + -7x) + 2x * (3 + x)) = 4 (-21 + -7x + (3 * 2x + x * 2x)) = 4 (-21 + -7x + (6x + 2x2)) = 4 Combine like terms: -7x + 6x = -1x (-21 + -1x + 2x2) = 4 Solving -21 + -1x + 2x2 = 4 Solving for variable 'x'. Reorder the terms: -21 + -4 + -1x + 2x2 = 4 + -4 Combine like terms: -21 + -4 = -25 -25 + -1x + 2x2 = 4 + -4 Combine like terms: 4 + -4 = 0 -25 + -1x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -12.5 + -0.5x + x2 = 0 Move the constant term to the right: Add '12.5' to each side of the equation. -12.5 + -0.5x + 12.5 + x2 = 0 + 12.5 Reorder the terms: -12.5 + 12.5 + -0.5x + x2 = 0 + 12.5 Combine like terms: -12.5 + 12.5 = 0.0 0.0 + -0.5x + x2 = 0 + 12.5 -0.5x + x2 = 0 + 12.5 Combine like terms: 0 + 12.5 = 12.5 -0.5x + x2 = 12.5 The x term is -0.5x. Take half its coefficient (-0.25). Square it (0.0625) and add it to both sides. Add '0.0625' to each side of the equation. -0.5x + 0.0625 + x2 = 12.5 + 0.0625 Reorder the terms: 0.0625 + -0.5x + x2 = 12.5 + 0.0625 Combine like terms: 12.5 + 0.0625 = 12.5625 0.0625 + -0.5x + x2 = 12.5625 Factor a perfect square on the left side: (x + -0.25)(x + -0.25) = 12.5625 Calculate the square root of the right side: 3.54436172 Break this problem into two subproblems by setting (x + -0.25) equal to 3.54436172 and -3.54436172.Subproblem 1
x + -0.25 = 3.54436172 Simplifying x + -0.25 = 3.54436172 Reorder the terms: -0.25 + x = 3.54436172 Solving -0.25 + x = 3.54436172 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.25' to each side of the equation. -0.25 + 0.25 + x = 3.54436172 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + x = 3.54436172 + 0.25 x = 3.54436172 + 0.25 Combine like terms: 3.54436172 + 0.25 = 3.79436172 x = 3.79436172 Simplifying x = 3.79436172Subproblem 2
x + -0.25 = -3.54436172 Simplifying x + -0.25 = -3.54436172 Reorder the terms: -0.25 + x = -3.54436172 Solving -0.25 + x = -3.54436172 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.25' to each side of the equation. -0.25 + 0.25 + x = -3.54436172 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + x = -3.54436172 + 0.25 x = -3.54436172 + 0.25 Combine like terms: -3.54436172 + 0.25 = -3.29436172 x = -3.29436172 Simplifying x = -3.29436172Solution
The solution to the problem is based on the solutions from the subproblems. x = {3.79436172, -3.29436172}
