Simplifying 5x2 + 9x = 7 Reorder the terms: 9x + 5x2 = 7 Solving 9x + 5x2 = 7 Solving for variable 'x'. Reorder the terms: -7 + 9x + 5x2 = 7 + -7 Combine like terms: 7 + -7 = 0 -7 + 9x + 5x2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -1.4 + 1.8x + x2 = 0 Move the constant term to the right: Add '1.4' to each side of the equation. -1.4 + 1.8x + 1.4 + x2 = 0 + 1.4 Reorder the terms: -1.4 + 1.4 + 1.8x + x2 = 0 + 1.4 Combine like terms: -1.4 + 1.4 = 0.0 0.0 + 1.8x + x2 = 0 + 1.4 1.8x + x2 = 0 + 1.4 Combine like terms: 0 + 1.4 = 1.4 1.8x + x2 = 1.4 The x term is 1.8x. Take half its coefficient (0.9). Square it (0.81) and add it to both sides. Add '0.81' to each side of the equation. 1.8x + 0.81 + x2 = 1.4 + 0.81 Reorder the terms: 0.81 + 1.8x + x2 = 1.4 + 0.81 Combine like terms: 1.4 + 0.81 = 2.21 0.81 + 1.8x + x2 = 2.21 Factor a perfect square on the left side: (x + 0.9)(x + 0.9) = 2.21 Calculate the square root of the right side: 1.486606875 Break this problem into two subproblems by setting (x + 0.9) equal to 1.486606875 and -1.486606875.Subproblem 1
x + 0.9 = 1.486606875 Simplifying x + 0.9 = 1.486606875 Reorder the terms: 0.9 + x = 1.486606875 Solving 0.9 + x = 1.486606875 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.9' to each side of the equation. 0.9 + -0.9 + x = 1.486606875 + -0.9 Combine like terms: 0.9 + -0.9 = 0.0 0.0 + x = 1.486606875 + -0.9 x = 1.486606875 + -0.9 Combine like terms: 1.486606875 + -0.9 = 0.586606875 x = 0.586606875 Simplifying x = 0.586606875Subproblem 2
x + 0.9 = -1.486606875 Simplifying x + 0.9 = -1.486606875 Reorder the terms: 0.9 + x = -1.486606875 Solving 0.9 + x = -1.486606875 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.9' to each side of the equation. 0.9 + -0.9 + x = -1.486606875 + -0.9 Combine like terms: 0.9 + -0.9 = 0.0 0.0 + x = -1.486606875 + -0.9 x = -1.486606875 + -0.9 Combine like terms: -1.486606875 + -0.9 = -2.386606875 x = -2.386606875 Simplifying x = -2.386606875Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.586606875, -2.386606875}
