Simplifying (2x + 3)(x + -3) = 25 Reorder the terms: (3 + 2x)(x + -3) = 25 Reorder the terms: (3 + 2x)(-3 + x) = 25 Multiply (3 + 2x) * (-3 + x) (3(-3 + x) + 2x * (-3 + x)) = 25 ((-3 * 3 + x * 3) + 2x * (-3 + x)) = 25 ((-9 + 3x) + 2x * (-3 + x)) = 25 (-9 + 3x + (-3 * 2x + x * 2x)) = 25 (-9 + 3x + (-6x + 2x2)) = 25 Combine like terms: 3x + -6x = -3x (-9 + -3x + 2x2) = 25 Solving -9 + -3x + 2x2 = 25 Solving for variable 'x'. Reorder the terms: -9 + -25 + -3x + 2x2 = 25 + -25 Combine like terms: -9 + -25 = -34 -34 + -3x + 2x2 = 25 + -25 Combine like terms: 25 + -25 = 0 -34 + -3x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -17 + -1.5x + x2 = 0 Move the constant term to the right: Add '17' to each side of the equation. -17 + -1.5x + 17 + x2 = 0 + 17 Reorder the terms: -17 + 17 + -1.5x + x2 = 0 + 17 Combine like terms: -17 + 17 = 0 0 + -1.5x + x2 = 0 + 17 -1.5x + x2 = 0 + 17 Combine like terms: 0 + 17 = 17 -1.5x + x2 = 17 The x term is -1.5x. Take half its coefficient (-0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. -1.5x + 0.5625 + x2 = 17 + 0.5625 Reorder the terms: 0.5625 + -1.5x + x2 = 17 + 0.5625 Combine like terms: 17 + 0.5625 = 17.5625 0.5625 + -1.5x + x2 = 17.5625 Factor a perfect square on the left side: (x + -0.75)(x + -0.75) = 17.5625 Calculate the square root of the right side: 4.190763654 Break this problem into two subproblems by setting (x + -0.75) equal to 4.190763654 and -4.190763654.Subproblem 1
x + -0.75 = 4.190763654 Simplifying x + -0.75 = 4.190763654 Reorder the terms: -0.75 + x = 4.190763654 Solving -0.75 + x = 4.190763654 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + x = 4.190763654 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + x = 4.190763654 + 0.75 x = 4.190763654 + 0.75 Combine like terms: 4.190763654 + 0.75 = 4.940763654 x = 4.940763654 Simplifying x = 4.940763654Subproblem 2
x + -0.75 = -4.190763654 Simplifying x + -0.75 = -4.190763654 Reorder the terms: -0.75 + x = -4.190763654 Solving -0.75 + x = -4.190763654 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + x = -4.190763654 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + x = -4.190763654 + 0.75 x = -4.190763654 + 0.75 Combine like terms: -4.190763654 + 0.75 = -3.440763654 x = -3.440763654 Simplifying x = -3.440763654Solution
