Simplifying 3 = (4x + 1)(x + -7) Reorder the terms: 3 = (1 + 4x)(x + -7) Reorder the terms: 3 = (1 + 4x)(-7 + x) Multiply (1 + 4x) * (-7 + x) 3 = (1(-7 + x) + 4x * (-7 + x)) 3 = ((-7 * 1 + x * 1) + 4x * (-7 + x)) 3 = ((-7 + 1x) + 4x * (-7 + x)) 3 = (-7 + 1x + (-7 * 4x + x * 4x)) 3 = (-7 + 1x + (-28x + 4x2)) Combine like terms: 1x + -28x = -27x 3 = (-7 + -27x + 4x2) Solving 3 = -7 + -27x + 4x2 Solving for variable 'x'. Combine like terms: 3 + 7 = 10 10 + 27x + -4x2 = -7 + -27x + 4x2 + 7 + 27x + -4x2 Reorder the terms: 10 + 27x + -4x2 = -7 + 7 + -27x + 27x + 4x2 + -4x2 Combine like terms: -7 + 7 = 0 10 + 27x + -4x2 = 0 + -27x + 27x + 4x2 + -4x2 10 + 27x + -4x2 = -27x + 27x + 4x2 + -4x2 Combine like terms: -27x + 27x = 0 10 + 27x + -4x2 = 0 + 4x2 + -4x2 10 + 27x + -4x2 = 4x2 + -4x2 Combine like terms: 4x2 + -4x2 = 0 10 + 27x + -4x2 = 0 Begin completing the square. Divide all terms by -4 the coefficient of the squared term: Divide each side by '-4'. -2.5 + -6.75x + x2 = 0 Move the constant term to the right: Add '2.5' to each side of the equation. -2.5 + -6.75x + 2.5 + x2 = 0 + 2.5 Reorder the terms: -2.5 + 2.5 + -6.75x + x2 = 0 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + -6.75x + x2 = 0 + 2.5 -6.75x + x2 = 0 + 2.5 Combine like terms: 0 + 2.5 = 2.5 -6.75x + x2 = 2.5 The x term is -6.75x. Take half its coefficient (-3.375). Square it (11.390625) and add it to both sides. Add '11.390625' to each side of the equation. -6.75x + 11.390625 + x2 = 2.5 + 11.390625 Reorder the terms: 11.390625 + -6.75x + x2 = 2.5 + 11.390625 Combine like terms: 2.5 + 11.390625 = 13.890625 11.390625 + -6.75x + x2 = 13.890625 Factor a perfect square on the left side: (x + -3.375)(x + -3.375) = 13.890625 Calculate the square root of the right side: 3.727012879 Break this problem into two subproblems by setting (x + -3.375) equal to 3.727012879 and -3.727012879.Subproblem 1
x + -3.375 = 3.727012879 Simplifying x + -3.375 = 3.727012879 Reorder the terms: -3.375 + x = 3.727012879 Solving -3.375 + x = 3.727012879 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3.375' to each side of the equation. -3.375 + 3.375 + x = 3.727012879 + 3.375 Combine like terms: -3.375 + 3.375 = 0.000 0.000 + x = 3.727012879 + 3.375 x = 3.727012879 + 3.375 Combine like terms: 3.727012879 + 3.375 = 7.102012879 x = 7.102012879 Simplifying x = 7.102012879Subproblem 2
x + -3.375 = -3.727012879 Simplifying x + -3.375 = -3.727012879 Reorder the terms: -3.375 + x = -3.727012879 Solving -3.375 + x = -3.727012879 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3.375' to each side of the equation. -3.375 + 3.375 + x = -3.727012879 + 3.375 Combine like terms: -3.375 + 3.375 = 0.000 0.000 + x = -3.727012879 + 3.375 x = -3.727012879 + 3.375 Combine like terms: -3.727012879 + 3.375 = -0.352012879 x = -0.352012879 Simplifying x = -0.352012879Solution
