Simplifying 2x2 + 12x = 9 Reorder the terms: 12x + 2x2 = 9 Solving 12x + 2x2 = 9 Solving for variable 'x'. Reorder the terms: -9 + 12x + 2x2 = 9 + -9 Combine like terms: 9 + -9 = 0 -9 + 12x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -4.5 + 6x + x2 = 0 Move the constant term to the right: Add '4.5' to each side of the equation. -4.5 + 6x + 4.5 + x2 = 0 + 4.5 Reorder the terms: -4.5 + 4.5 + 6x + x2 = 0 + 4.5 Combine like terms: -4.5 + 4.5 = 0.0 0.0 + 6x + x2 = 0 + 4.5 6x + x2 = 0 + 4.5 Combine like terms: 0 + 4.5 = 4.5 6x + x2 = 4.5 The x term is 6x. Take half its coefficient (3). Square it (9) and add it to both sides. Add '9' to each side of the equation. 6x + 9 + x2 = 4.5 + 9 Reorder the terms: 9 + 6x + x2 = 4.5 + 9 Combine like terms: 4.5 + 9 = 13.5 9 + 6x + x2 = 13.5 Factor a perfect square on the left side: (x + 3)(x + 3) = 13.5 Calculate the square root of the right side: 3.674234614 Break this problem into two subproblems by setting (x + 3) equal to 3.674234614 and -3.674234614.Subproblem 1
x + 3 = 3.674234614 Simplifying x + 3 = 3.674234614 Reorder the terms: 3 + x = 3.674234614 Solving 3 + x = 3.674234614 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + x = 3.674234614 + -3 Combine like terms: 3 + -3 = 0 0 + x = 3.674234614 + -3 x = 3.674234614 + -3 Combine like terms: 3.674234614 + -3 = 0.674234614 x = 0.674234614 Simplifying x = 0.674234614Subproblem 2
x + 3 = -3.674234614 Simplifying x + 3 = -3.674234614 Reorder the terms: 3 + x = -3.674234614 Solving 3 + x = -3.674234614 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + x = -3.674234614 + -3 Combine like terms: 3 + -3 = 0 0 + x = -3.674234614 + -3 x = -3.674234614 + -3 Combine like terms: -3.674234614 + -3 = -6.674234614 x = -6.674234614 Simplifying x = -6.674234614Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.674234614, -6.674234614}
