Simplifying 25x2 + 350x + 49 = 0 Reorder the terms: 49 + 350x + 25x2 = 0 Solving 49 + 350x + 25x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 25 the coefficient of the squared term: Divide each side by '25'. 1.96 + 14x + x2 = 0 Move the constant term to the right: Add '-1.96' to each side of the equation. 1.96 + 14x + -1.96 + x2 = 0 + -1.96 Reorder the terms: 1.96 + -1.96 + 14x + x2 = 0 + -1.96 Combine like terms: 1.96 + -1.96 = 0.00 0.00 + 14x + x2 = 0 + -1.96 14x + x2 = 0 + -1.96 Combine like terms: 0 + -1.96 = -1.96 14x + x2 = -1.96 The x term is 14x. Take half its coefficient (7). Square it (49) and add it to both sides. Add '49' to each side of the equation. 14x + 49 + x2 = -1.96 + 49 Reorder the terms: 49 + 14x + x2 = -1.96 + 49 Combine like terms: -1.96 + 49 = 47.04 49 + 14x + x2 = 47.04 Factor a perfect square on the left side: (x + 7)(x + 7) = 47.04 Calculate the square root of the right side: 6.85857128 Break this problem into two subproblems by setting (x + 7) equal to 6.85857128 and -6.85857128.Subproblem 1
x + 7 = 6.85857128 Simplifying x + 7 = 6.85857128 Reorder the terms: 7 + x = 6.85857128 Solving 7 + x = 6.85857128 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + x = 6.85857128 + -7 Combine like terms: 7 + -7 = 0 0 + x = 6.85857128 + -7 x = 6.85857128 + -7 Combine like terms: 6.85857128 + -7 = -0.14142872 x = -0.14142872 Simplifying x = -0.14142872Subproblem 2
x + 7 = -6.85857128 Simplifying x + 7 = -6.85857128 Reorder the terms: 7 + x = -6.85857128 Solving 7 + x = -6.85857128 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + x = -6.85857128 + -7 Combine like terms: 7 + -7 = 0 0 + x = -6.85857128 + -7 x = -6.85857128 + -7 Combine like terms: -6.85857128 + -7 = -13.85857128 x = -13.85857128 Simplifying x = -13.85857128Solution
