Simplifying (4x + 9)(x + -4) = 16 + 36 Reorder the terms: (9 + 4x)(x + -4) = 16 + 36 Reorder the terms: (9 + 4x)(-4 + x) = 16 + 36 Multiply (9 + 4x) * (-4 + x) (9(-4 + x) + 4x * (-4 + x)) = 16 + 36 ((-4 * 9 + x * 9) + 4x * (-4 + x)) = 16 + 36 ((-36 + 9x) + 4x * (-4 + x)) = 16 + 36 (-36 + 9x + (-4 * 4x + x * 4x)) = 16 + 36 (-36 + 9x + (-16x + 4x2)) = 16 + 36 Combine like terms: 9x + -16x = -7x (-36 + -7x + 4x2) = 16 + 36 Combine like terms: 16 + 36 = 52 -36 + -7x + 4x2 = 52 Solving -36 + -7x + 4x2 = 52 Solving for variable 'x'. Reorder the terms: -36 + -52 + -7x + 4x2 = 52 + -52 Combine like terms: -36 + -52 = -88 -88 + -7x + 4x2 = 52 + -52 Combine like terms: 52 + -52 = 0 -88 + -7x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -22 + -1.75x + x2 = 0 Move the constant term to the right: Add '22' to each side of the equation. -22 + -1.75x + 22 + x2 = 0 + 22 Reorder the terms: -22 + 22 + -1.75x + x2 = 0 + 22 Combine like terms: -22 + 22 = 0 0 + -1.75x + x2 = 0 + 22 -1.75x + x2 = 0 + 22 Combine like terms: 0 + 22 = 22 -1.75x + x2 = 22 The x term is -1.75x. Take half its coefficient (-0.875). Square it (0.765625) and add it to both sides. Add '0.765625' to each side of the equation. -1.75x + 0.765625 + x2 = 22 + 0.765625 Reorder the terms: 0.765625 + -1.75x + x2 = 22 + 0.765625 Combine like terms: 22 + 0.765625 = 22.765625 0.765625 + -1.75x + x2 = 22.765625 Factor a perfect square on the left side: (x + -0.875)(x + -0.875) = 22.765625 Calculate the square root of the right side: 4.771333671 Break this problem into two subproblems by setting (x + -0.875) equal to 4.771333671 and -4.771333671.Subproblem 1
x + -0.875 = 4.771333671 Simplifying x + -0.875 = 4.771333671 Reorder the terms: -0.875 + x = 4.771333671 Solving -0.875 + x = 4.771333671 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.875' to each side of the equation. -0.875 + 0.875 + x = 4.771333671 + 0.875 Combine like terms: -0.875 + 0.875 = 0.000 0.000 + x = 4.771333671 + 0.875 x = 4.771333671 + 0.875 Combine like terms: 4.771333671 + 0.875 = 5.646333671 x = 5.646333671 Simplifying x = 5.646333671Subproblem 2
x + -0.875 = -4.771333671 Simplifying x + -0.875 = -4.771333671 Reorder the terms: -0.875 + x = -4.771333671 Solving -0.875 + x = -4.771333671 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.875' to each side of the equation. -0.875 + 0.875 + x = -4.771333671 + 0.875 Combine like terms: -0.875 + 0.875 = 0.000 0.000 + x = -4.771333671 + 0.875 x = -4.771333671 + 0.875 Combine like terms: -4.771333671 + 0.875 = -3.896333671 x = -3.896333671 Simplifying x = -3.896333671Solution
