Simplifying (2X2 + -13X + 7) + -1(1 + 12X) = 0 Reorder the terms: (7 + -13X + 2X2) + -1(1 + 12X) = 0 Remove parenthesis around (7 + -13X + 2X2) 7 + -13X + 2X2 + -1(1 + 12X) = 0 7 + -13X + 2X2 + (1 * -1 + 12X * -1) = 0 7 + -13X + 2X2 + (-1 + -12X) = 0 Reorder the terms: 7 + -1 + -13X + -12X + 2X2 = 0 Combine like terms: 7 + -1 = 6 6 + -13X + -12X + 2X2 = 0 Combine like terms: -13X + -12X = -25X 6 + -25X + 2X2 = 0 Solving 6 + -25X + 2X2 = 0 Solving for variable 'X'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 3 + -12.5X + X2 = 0 Move the constant term to the right: Add '-3' to each side of the equation. 3 + -12.5X + -3 + X2 = 0 + -3 Reorder the terms: 3 + -3 + -12.5X + X2 = 0 + -3 Combine like terms: 3 + -3 = 0 0 + -12.5X + X2 = 0 + -3 -12.5X + X2 = 0 + -3 Combine like terms: 0 + -3 = -3 -12.5X + X2 = -3 The X term is -12.5X. Take half its coefficient (-6.25). Square it (39.0625) and add it to both sides. Add '39.0625' to each side of the equation. -12.5X + 39.0625 + X2 = -3 + 39.0625 Reorder the terms: 39.0625 + -12.5X + X2 = -3 + 39.0625 Combine like terms: -3 + 39.0625 = 36.0625 39.0625 + -12.5X + X2 = 36.0625 Factor a perfect square on the left side: (X + -6.25)(X + -6.25) = 36.0625 Calculate the square root of the right side: 6.005206075 Break this problem into two subproblems by setting (X + -6.25) equal to 6.005206075 and -6.005206075.Subproblem 1
X + -6.25 = 6.005206075 Simplifying X + -6.25 = 6.005206075 Reorder the terms: -6.25 + X = 6.005206075 Solving -6.25 + X = 6.005206075 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '6.25' to each side of the equation. -6.25 + 6.25 + X = 6.005206075 + 6.25 Combine like terms: -6.25 + 6.25 = 0.00 0.00 + X = 6.005206075 + 6.25 X = 6.005206075 + 6.25 Combine like terms: 6.005206075 + 6.25 = 12.255206075 X = 12.255206075 Simplifying X = 12.255206075Subproblem 2
X + -6.25 = -6.005206075 Simplifying X + -6.25 = -6.005206075 Reorder the terms: -6.25 + X = -6.005206075 Solving -6.25 + X = -6.005206075 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '6.25' to each side of the equation. -6.25 + 6.25 + X = -6.005206075 + 6.25 Combine like terms: -6.25 + 6.25 = 0.00 0.00 + X = -6.005206075 + 6.25 X = -6.005206075 + 6.25 Combine like terms: -6.005206075 + 6.25 = 0.244793925 X = 0.244793925 Simplifying X = 0.244793925Solution
