Simplifying 4x2 + 2.4x + 0.36 = 9.7 Reorder the terms: 0.36 + 2.4x + 4x2 = 9.7 Solving 0.36 + 2.4x + 4x2 = 9.7 Solving for variable 'x'. Reorder the terms: 0.36 + -9.7 + 2.4x + 4x2 = 9.7 + -9.7 Combine like terms: 0.36 + -9.7 = -9.34 -9.34 + 2.4x + 4x2 = 9.7 + -9.7 Combine like terms: 9.7 + -9.7 = 0.0 -9.34 + 2.4x + 4x2 = 0.0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -2.335 + 0.6x + x2 = 0.0 Move the constant term to the right: Add '2.335' to each side of the equation. -2.335 + 0.6x + 2.335 + x2 = 0.0 + 2.335 Reorder the terms: -2.335 + 2.335 + 0.6x + x2 = 0.0 + 2.335 Combine like terms: -2.335 + 2.335 = 0.000 0.000 + 0.6x + x2 = 0.0 + 2.335 0.6x + x2 = 0.0 + 2.335 Combine like terms: 0.0 + 2.335 = 2.335 0.6x + x2 = 2.335 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 = 2.335 + 0.09 Reorder the terms: 0.09 + 0.6x + x2 = 2.335 + 0.09 Combine like terms: 2.335 + 0.09 = 2.425 0.09 + 0.6x + x2 = 2.425 Factor a perfect square on the left side: (x + 0.3)(x + 0.3) = 2.425 Calculate the square root of the right side: 1.55724115 Break this problem into two subproblems by setting (x + 0.3) equal to 1.55724115 and -1.55724115.Subproblem 1
x + 0.3 = 1.55724115 Simplifying x + 0.3 = 1.55724115 Reorder the terms: 0.3 + x = 1.55724115 Solving 0.3 + x = 1.55724115 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 = 1.55724115 + -0.3 Combine like terms: 0.3 + -0.3 = 0.0 0.0 + x = 1.55724115 + -0.3 x = 1.55724115 + -0.3 Combine like terms: 1.55724115 + -0.3 = 1.25724115 x = 1.25724115 Simplifying x = 1.25724115Subproblem 2
x + 0.3 = -1.55724115 Simplifying x + 0.3 = -1.55724115 Reorder the terms: 0.3 + x = -1.55724115 Solving 0.3 + x = -1.55724115 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 = -1.55724115 + -0.3 Combine like terms: 0.3 + -0.3 = 0.0 0.0 + x = -1.55724115 + -0.3 x = -1.55724115 + -0.3 Combine like terms: -1.55724115 + -0.3 = -1.85724115 x = -1.85724115 Simplifying x = -1.85724115Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.25724115, -1.85724115}
