Simplifying 15x2 + 9x + -4 = 0 Reorder the terms: -4 + 9x + 15x2 = 0 Solving -4 + 9x + 15x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 15 the coefficient of the squared term: Divide each side by '15'. -0.2666666667 + 0.6x + x2 = 0 Move the constant term to the right: Add '0.2666666667' to each side of the equation. -0.2666666667 + 0.6x + 0.2666666667 + x2 = 0 + 0.2666666667 Reorder the terms: -0.2666666667 + 0.2666666667 + 0.6x + x2 = 0 + 0.2666666667 Combine like terms: -0.2666666667 + 0.2666666667 = 0.0000000000 0.0000000000 + 0.6x + x2 = 0 + 0.2666666667 0.6x + x2 = 0 + 0.2666666667 Combine like terms: 0 + 0.2666666667 = 0.2666666667 0.6x + x2 = 0.2666666667 The x term is 0.6x. Take half its coefficient (0.3). Square it (0.09) and add it to both sides. Add '0.09' to each side of the equation. 0.6x + 0.09 + x2 = 0.2666666667 + 0.09 Reorder the terms: 0.09 + 0.6x + x2 = 0.2666666667 + 0.09 Combine like terms: 0.2666666667 + 0.09 = 0.3566666667 0.09 + 0.6x + x2 = 0.3566666667 Factor a perfect square on the left side: (x + 0.3)(x + 0.3) = 0.3566666667 Calculate the square root of the right side: 0.597215762 Break this problem into two subproblems by setting (x + 0.3) equal to 0.597215762 and -0.597215762.Subproblem 1
x + 0.3 = 0.597215762 Simplifying x + 0.3 = 0.597215762 Reorder the terms: 0.3 + x = 0.597215762 Solving 0.3 + x = 0.597215762 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.3' to each side of the equation. 0.3 + -0.3 + x = 0.597215762 + -0.3 Combine like terms: 0.3 + -0.3 = 0.0 0.0 + x = 0.597215762 + -0.3 x = 0.597215762 + -0.3 Combine like terms: 0.597215762 + -0.3 = 0.297215762 x = 0.297215762 Simplifying x = 0.297215762Subproblem 2
x + 0.3 = -0.597215762 Simplifying x + 0.3 = -0.597215762 Reorder the terms: 0.3 + x = -0.597215762 Solving 0.3 + x = -0.597215762 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.3' to each side of the equation. 0.3 + -0.3 + x = -0.597215762 + -0.3 Combine like terms: 0.3 + -0.3 = 0.0 0.0 + x = -0.597215762 + -0.3 x = -0.597215762 + -0.3 Combine like terms: -0.597215762 + -0.3 = -0.897215762 x = -0.897215762 Simplifying x = -0.897215762Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.297215762, -0.897215762}
