Simplifying 2x2 + -30x + 9 = -12 Reorder the terms: 9 + -30x + 2x2 = -12 Solving 9 + -30x + 2x2 = -12 Solving for variable 'x'. Reorder the terms: 9 + 12 + -30x + 2x2 = -12 + 12 Combine like terms: 9 + 12 = 21 21 + -30x + 2x2 = -12 + 12 Combine like terms: -12 + 12 = 0 21 + -30x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 10.5 + -15x + x2 = 0 Move the constant term to the right: Add '-10.5' to each side of the equation. 10.5 + -15x + -10.5 + x2 = 0 + -10.5 Reorder the terms: 10.5 + -10.5 + -15x + x2 = 0 + -10.5 Combine like terms: 10.5 + -10.5 = 0.0 0.0 + -15x + x2 = 0 + -10.5 -15x + x2 = 0 + -10.5 Combine like terms: 0 + -10.5 = -10.5 -15x + x2 = -10.5 The x term is -15x. Take half its coefficient (-7.5). Square it (56.25) and add it to both sides. Add '56.25' to each side of the equation. -15x + 56.25 + x2 = -10.5 + 56.25 Reorder the terms: 56.25 + -15x + x2 = -10.5 + 56.25 Combine like terms: -10.5 + 56.25 = 45.75 56.25 + -15x + x2 = 45.75 Factor a perfect square on the left side: (x + -7.5)(x + -7.5) = 45.75 Calculate the square root of the right side: 6.763874629 Break this problem into two subproblems by setting (x + -7.5) equal to 6.763874629 and -6.763874629.Subproblem 1
