Simplifying 4X * 4X = 13X + 12 Reorder the terms for easier multiplication: 4 * 4X * X = 13X + 12 Multiply 4 * 4 16X * X = 13X + 12 Multiply X * X 16X2 = 13X + 12 Reorder the terms: 16X2 = 12 + 13X Solving 16X2 = 12 + 13X Solving for variable 'X'. Reorder the terms: -12 + -13X + 16X2 = 12 + 13X + -12 + -13X Reorder the terms: -12 + -13X + 16X2 = 12 + -12 + 13X + -13X Combine like terms: 12 + -12 = 0 -12 + -13X + 16X2 = 0 + 13X + -13X -12 + -13X + 16X2 = 13X + -13X Combine like terms: 13X + -13X = 0 -12 + -13X + 16X2 = 0 Begin completing the square. Divide all terms by 16 the coefficient of the squared term: Divide each side by '16'. -0.75 + -0.8125X + X2 = 0 Move the constant term to the right: Add '0.75' to each side of the equation. -0.75 + -0.8125X + 0.75 + X2 = 0 + 0.75 Reorder the terms: -0.75 + 0.75 + -0.8125X + X2 = 0 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + -0.8125X + X2 = 0 + 0.75 -0.8125X + X2 = 0 + 0.75 Combine like terms: 0 + 0.75 = 0.75 -0.8125X + X2 = 0.75 The X term is -0.8125X. Take half its coefficient (-0.40625). Square it (0.1650390625) and add it to both sides. Add '0.1650390625' to each side of the equation. -0.8125X + 0.1650390625 + X2 = 0.75 + 0.1650390625 Reorder the terms: 0.1650390625 + -0.8125X + X2 = 0.75 + 0.1650390625 Combine like terms: 0.75 + 0.1650390625 = 0.9150390625 0.1650390625 + -0.8125X + X2 = 0.9150390625 Factor a perfect square on the left side: (X + -0.40625)(X + -0.40625) = 0.9150390625 Calculate the square root of the right side: 0.956576742 Break this problem into two subproblems by setting (X + -0.40625) equal to 0.956576742 and -0.956576742.Subproblem 1
X + -0.40625 = 0.956576742 Simplifying X + -0.40625 = 0.956576742 Reorder the terms: -0.40625 + X = 0.956576742 Solving -0.40625 + X = 0.956576742 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '0.40625' to each side of the equation. -0.40625 + 0.40625 + X = 0.956576742 + 0.40625 Combine like terms: -0.40625 + 0.40625 = 0.00000 0.00000 + X = 0.956576742 + 0.40625 X = 0.956576742 + 0.40625 Combine like terms: 0.956576742 + 0.40625 = 1.362826742 X = 1.362826742 Simplifying X = 1.362826742Subproblem 2
X + -0.40625 = -0.956576742 Simplifying X + -0.40625 = -0.956576742 Reorder the terms: -0.40625 + X = -0.956576742 Solving -0.40625 + X = -0.956576742 Solving for variable 'X'.
