Simplifying 8x2 + 12x + -30 = 4x + 3 Reorder the terms: -30 + 12x + 8x2 = 4x + 3 Reorder the terms: -30 + 12x + 8x2 = 3 + 4x Solving -30 + 12x + 8x2 = 3 + 4x Solving for variable 'x'. Reorder the terms: -30 + -3 + 12x + -4x + 8x2 = 3 + 4x + -3 + -4x Combine like terms: -30 + -3 = -33 -33 + 12x + -4x + 8x2 = 3 + 4x + -3 + -4x Combine like terms: 12x + -4x = 8x -33 + 8x + 8x2 = 3 + 4x + -3 + -4x Reorder the terms: -33 + 8x + 8x2 = 3 + -3 + 4x + -4x Combine like terms: 3 + -3 = 0 -33 + 8x + 8x2 = 0 + 4x + -4x -33 + 8x + 8x2 = 4x + -4x Combine like terms: 4x + -4x = 0 -33 + 8x + 8x2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. -4.125 + x + x2 = 0 Move the constant term to the right: Add '4.125' to each side of the equation. -4.125 + x + 4.125 + x2 = 0 + 4.125 Reorder the terms: -4.125 + 4.125 + x + x2 = 0 + 4.125 Combine like terms: -4.125 + 4.125 = 0.000 0.000 + x + x2 = 0 + 4.125 x + x2 = 0 + 4.125 Combine like terms: 0 + 4.125 = 4.125 x + x2 = 4.125 The x term is x. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. + 0.25 + x2 = 4.125 + 0.25 Combine like terms: + 0.25 = 1.25 1.25 + x2 = 4.125 + 0.25 Combine like terms: 4.125 + 0.25 = 4.375 1.25 + x2 = 4.375 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = 4.375 Calculate the square root of the right side: 2.091650066 Break this problem into two subproblems by setting (x + 0.5) equal to 2.091650066 and -2.091650066.Subproblem 1
x + 0.5 = 2.091650066 Simplifying x + 0.5 = 2.091650066 Reorder the terms: 0.5 + x = 2.091650066 Solving 0.5 + x = 2.091650066 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = 2.091650066 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = 2.091650066 + -0.5 x = 2.091650066 + -0.5 Combine like terms: 2.091650066 + -0.5 = 1.591650066 x = 1.591650066 Simplifying x = 1.591650066Subproblem 2
x + 0.5 = -2.091650066 Simplifying x + 0.5 = -2.091650066 Reorder the terms: 0.5 + x = -2.091650066 Solving 0.5 + x = -2.091650066 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = -2.091650066 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = -2.091650066 + -0.5 x = -2.091650066 + -0.5 Combine like terms: -2.091650066 + -0.5 = -2.591650066 x = -2.591650066 Simplifying x = -2.591650066Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.591650066, -2.591650066}
