Simplifying 20x2 + 30x + 9 = 0 Reorder the terms: 9 + 30x + 20x2 = 0 Solving 9 + 30x + 20x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 20 the coefficient of the squared term: Divide each side by '20'. 0.45 + 1.5x + x2 = 0 Move the constant term to the right: Add '-0.45' to each side of the equation. 0.45 + 1.5x + -0.45 + x2 = 0 + -0.45 Reorder the terms: 0.45 + -0.45 + 1.5x + x2 = 0 + -0.45 Combine like terms: 0.45 + -0.45 = 0.00 0.00 + 1.5x + x2 = 0 + -0.45 1.5x + x2 = 0 + -0.45 Combine like terms: 0 + -0.45 = -0.45 1.5x + x2 = -0.45 The x term is 1.5x. Take half its coefficient (0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. 1.5x + 0.5625 + x2 = -0.45 + 0.5625 Reorder the terms: 0.5625 + 1.5x + x2 = -0.45 + 0.5625 Combine like terms: -0.45 + 0.5625 = 0.1125 0.5625 + 1.5x + x2 = 0.1125 Factor a perfect square on the left side: (x + 0.75)(x + 0.75) = 0.1125 Calculate the square root of the right side: 0.335410197 Break this problem into two subproblems by setting (x + 0.75) equal to 0.335410197 and -0.335410197.Subproblem 1
x + 0.75 = 0.335410197 Simplifying x + 0.75 = 0.335410197 Reorder the terms: 0.75 + x = 0.335410197 Solving 0.75 + x = 0.335410197 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.75' to each side of the equation. 0.75 + -0.75 + x = 0.335410197 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + x = 0.335410197 + -0.75 x = 0.335410197 + -0.75 Combine like terms: 0.335410197 + -0.75 = -0.414589803 x = -0.414589803 Simplifying x = -0.414589803Subproblem 2
x + 0.75 = -0.335410197 Simplifying x + 0.75 = -0.335410197 Reorder the terms: 0.75 + x = -0.335410197 Solving 0.75 + x = -0.335410197 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.75' to each side of the equation. 0.75 + -0.75 + x = -0.335410197 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + x = -0.335410197 + -0.75 x = -0.335410197 + -0.75 Combine like terms: -0.335410197 + -0.75 = -1.085410197 x = -1.085410197 Simplifying x = -1.085410197Solution
