Simplifying 2x2 + 14x + 7x = 49 Reorder the terms: 14x + 7x + 2x2 = 49 Combine like terms: 14x + 7x = 21x 21x + 2x2 = 49 Solving 21x + 2x2 = 49 Solving for variable 'x'. Reorder the terms: -49 + 21x + 2x2 = 49 + -49 Combine like terms: 49 + -49 = 0 -49 + 21x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -24.5 + 10.5x + x2 = 0 Move the constant term to the right: Add '24.5' to each side of the equation. -24.5 + 10.5x + 24.5 + x2 = 0 + 24.5 Reorder the terms: -24.5 + 24.5 + 10.5x + x2 = 0 + 24.5 Combine like terms: -24.5 + 24.5 = 0.0 0.0 + 10.5x + x2 = 0 + 24.5 10.5x + x2 = 0 + 24.5 Combine like terms: 0 + 24.5 = 24.5 10.5x + x2 = 24.5 The x term is 10.5x. Take half its coefficient (5.25). Square it (27.5625) and add it to both sides. Add '27.5625' to each side of the equation. 10.5x + 27.5625 + x2 = 24.5 + 27.5625 Reorder the terms: 27.5625 + 10.5x + x2 = 24.5 + 27.5625 Combine like terms: 24.5 + 27.5625 = 52.0625 27.5625 + 10.5x + x2 = 52.0625 Factor a perfect square on the left side: (x + 5.25)(x + 5.25) = 52.0625 Calculate the square root of the right side: 7.215434845 Break this problem into two subproblems by setting (x + 5.25) equal to 7.215434845 and -7.215434845.Subproblem 1
