Simplifying 2x2 + 45 = 24x Reorder the terms: 45 + 2x2 = 24x Solving 45 + 2x2 = 24x Solving for variable 'x'. Reorder the terms: 45 + -24x + 2x2 = 24x + -24x Combine like terms: 24x + -24x = 0 45 + -24x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 22.5 + -12x + x2 = 0 Move the constant term to the right: Add '-22.5' to each side of the equation. 22.5 + -12x + -22.5 + x2 = 0 + -22.5 Reorder the terms: 22.5 + -22.5 + -12x + x2 = 0 + -22.5 Combine like terms: 22.5 + -22.5 = 0.0 0.0 + -12x + x2 = 0 + -22.5 -12x + x2 = 0 + -22.5 Combine like terms: 0 + -22.5 = -22.5 -12x + x2 = -22.5 The x term is -12x. Take half its coefficient (-6). Square it (36) and add it to both sides. Add '36' to each side of the equation. -12x + 36 + x2 = -22.5 + 36 Reorder the terms: 36 + -12x + x2 = -22.5 + 36 Combine like terms: -22.5 + 36 = 13.5 36 + -12x + x2 = 13.5 Factor a perfect square on the left side: (x + -6)(x + -6) = 13.5 Calculate the square root of the right side: 3.674234614 Break this problem into two subproblems by setting (x + -6) equal to 3.674234614 and -3.674234614.Subproblem 1
x + -6 = 3.674234614 Simplifying x + -6 = 3.674234614 Reorder the terms: -6 + x = 3.674234614 Solving -6 + x = 3.674234614 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '6' to each side of the equation. -6 + 6 + x = 3.674234614 + 6 Combine like terms: -6 + 6 = 0 0 + x = 3.674234614 + 6 x = 3.674234614 + 6 Combine like terms: 3.674234614 + 6 = 9.674234614 x = 9.674234614 Simplifying x = 9.674234614Subproblem 2
x + -6 = -3.674234614 Simplifying x + -6 = -3.674234614 Reorder the terms: -6 + x = -3.674234614 Solving -6 + x = -3.674234614 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '6' to each side of the equation. -6 + 6 + x = -3.674234614 + 6 Combine like terms: -6 + 6 = 0 0 + x = -3.674234614 + 6 x = -3.674234614 + 6 Combine like terms: -3.674234614 + 6 = 2.325765386 x = 2.325765386 Simplifying x = 2.325765386Solution
