Simplifying -4x2 = 7 + -27x Solving -4x2 = 7 + -27x Solving for variable 'x'. Reorder the terms: -7 + 27x + -4x2 = 7 + -27x + -7 + 27x Reorder the terms: -7 + 27x + -4x2 = 7 + -7 + -27x + 27x Combine like terms: 7 + -7 = 0 -7 + 27x + -4x2 = 0 + -27x + 27x -7 + 27x + -4x2 = -27x + 27x Combine like terms: -27x + 27x = 0 -7 + 27x + -4x2 = 0 Begin completing the square. Divide all terms by -4 the coefficient of the squared term: Divide each side by '-4'. 1.75 + -6.75x + x2 = 0 Move the constant term to the right: Add '-1.75' to each side of the equation. 1.75 + -6.75x + -1.75 + x2 = 0 + -1.75 Reorder the terms: 1.75 + -1.75 + -6.75x + x2 = 0 + -1.75 Combine like terms: 1.75 + -1.75 = 0.00 0.00 + -6.75x + x2 = 0 + -1.75 -6.75x + x2 = 0 + -1.75 Combine like terms: 0 + -1.75 = -1.75 -6.75x + x2 = -1.75 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 = -1.75 + 11.390625 Reorder the terms: 11.390625 + -6.75x + x2 = -1.75 + 11.390625 Combine like terms: -1.75 + 11.390625 = 9.640625 11.390625 + -6.75x + x2 = 9.640625 Factor a perfect square on the left side: (x + -3.375)(x + -3.375) = 9.640625 Calculate the square root of the right side: 3.104935587 Break this problem into two subproblems by setting (x + -3.375) equal to 3.104935587 and -3.104935587.Subproblem 1
