Simplifying 7x + 18 = (-2x + 3)(-2x + 3) Reorder the terms: 18 + 7x = (-2x + 3)(-2x + 3) Reorder the terms: 18 + 7x = (3 + -2x)(-2x + 3) Reorder the terms: 18 + 7x = (3 + -2x)(3 + -2x) Multiply (3 + -2x) * (3 + -2x) 18 + 7x = (3(3 + -2x) + -2x * (3 + -2x)) 18 + 7x = ((3 * 3 + -2x * 3) + -2x * (3 + -2x)) 18 + 7x = ((9 + -6x) + -2x * (3 + -2x)) 18 + 7x = (9 + -6x + (3 * -2x + -2x * -2x)) 18 + 7x = (9 + -6x + (-6x + 4x2)) Combine like terms: -6x + -6x = -12x 18 + 7x = (9 + -12x + 4x2) Solving 18 + 7x = 9 + -12x + 4x2 Solving for variable 'x'. Reorder the terms: 18 + -9 + 7x + 12x + -4x2 = 9 + -12x + 4x2 + -9 + 12x + -4x2 Combine like terms: 18 + -9 = 9 9 + 7x + 12x + -4x2 = 9 + -12x + 4x2 + -9 + 12x + -4x2 Combine like terms: 7x + 12x = 19x 9 + 19x + -4x2 = 9 + -12x + 4x2 + -9 + 12x + -4x2 Reorder the terms: 9 + 19x + -4x2 = 9 + -9 + -12x + 12x + 4x2 + -4x2 Combine like terms: 9 + -9 = 0 9 + 19x + -4x2 = 0 + -12x + 12x + 4x2 + -4x2 9 + 19x + -4x2 = -12x + 12x + 4x2 + -4x2 Combine like terms: -12x + 12x = 0 9 + 19x + -4x2 = 0 + 4x2 + -4x2 9 + 19x + -4x2 = 4x2 + -4x2 Combine like terms: 4x2 + -4x2 = 0 9 + 19x + -4x2 = 0 Begin completing the square. Divide all terms by -4 the coefficient of the squared term: Divide each side by '-4'. -2.25 + -4.75x + x2 = 0 Move the constant term to the right: Add '2.25' to each side of the equation. -2.25 + -4.75x + 2.25 + x2 = 0 + 2.25 Reorder the terms: -2.25 + 2.25 + -4.75x + x2 = 0 + 2.25 Combine like terms: -2.25 + 2.25 = 0.00 0.00 + -4.75x + x2 = 0 + 2.25 -4.75x + x2 = 0 + 2.25 Combine like terms: 0 + 2.25 = 2.25 -4.75x + x2 = 2.25 The x term is -4.75x. Take half its coefficient (-2.375). Square it (5.640625) and add it to both sides. Add '5.640625' to each side of the equation. -4.75x + 5.640625 + x2 = 2.25 + 5.640625 Reorder the terms: 5.640625 + -4.75x + x2 = 2.25 + 5.640625 Combine like terms: 2.25 + 5.640625 = 7.890625 5.640625 + -4.75x + x2 = 7.890625 Factor a perfect square on the left side: (x + -2.375)(x + -2.375) = 7.890625 Calculate the square root of the right side: 2.809025632 Break this problem into two subproblems by setting (x + -2.375) equal to 2.809025632 and -2.809025632.Subproblem 1
x + -2.375 = 2.809025632 Simplifying x + -2.375 = 2.809025632 Reorder the terms: -2.375 + x = 2.809025632 Solving -2.375 + x = 2.809025632 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.375' to each side of the equation. -2.375 + 2.375 + x = 2.809025632 + 2.375 Combine like terms: -2.375 + 2.375 = 0.000 0.000 + x = 2.809025632 + 2.375 x = 2.809025632 + 2.375 Combine like terms: 2.809025632 + 2.375 = 5.184025632 x = 5.184025632 Simplifying x = 5.184025632Subproblem 2
