Simplifying 5X2 + -66X + 1 = 0 Reorder the terms: 1 + -66X + 5X2 = 0 Solving 1 + -66X + 5X2 = 0 Solving for variable 'X'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 0.2 + -13.2X + X2 = 0 Move the constant term to the right: Add '-0.2' to each side of the equation. 0.2 + -13.2X + -0.2 + X2 = 0 + -0.2 Reorder the terms: 0.2 + -0.2 + -13.2X + X2 = 0 + -0.2 Combine like terms: 0.2 + -0.2 = 0.0 0.0 + -13.2X + X2 = 0 + -0.2 -13.2X + X2 = 0 + -0.2 Combine like terms: 0 + -0.2 = -0.2 -13.2X + X2 = -0.2 The X term is -13.2X. Take half its coefficient (-6.6). Square it (43.56) and add it to both sides. Add '43.56' to each side of the equation. -13.2X + 43.56 + X2 = -0.2 + 43.56 Reorder the terms: 43.56 + -13.2X + X2 = -0.2 + 43.56 Combine like terms: -0.2 + 43.56 = 43.36 43.56 + -13.2X + X2 = 43.36 Factor a perfect square on the left side: (X + -6.6)(X + -6.6) = 43.36 Calculate the square root of the right side: 6.584831053 Break this problem into two subproblems by setting (X + -6.6) equal to 6.584831053 and -6.584831053.Subproblem 1
X + -6.6 = 6.584831053 Simplifying X + -6.6 = 6.584831053 Reorder the terms: -6.6 + X = 6.584831053 Solving -6.6 + X = 6.584831053 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '6.6' to each side of the equation. -6.6 + 6.6 + X = 6.584831053 + 6.6 Combine like terms: -6.6 + 6.6 = 0.0 0.0 + X = 6.584831053 + 6.6 X = 6.584831053 + 6.6 Combine like terms: 6.584831053 + 6.6 = 13.184831053 X = 13.184831053 Simplifying X = 13.184831053Subproblem 2
X + -6.6 = -6.584831053 Simplifying X + -6.6 = -6.584831053 Reorder the terms: -6.6 + X = -6.584831053 Solving -6.6 + X = -6.584831053 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '6.6' to each side of the equation. -6.6 + 6.6 + X = -6.584831053 + 6.6 Combine like terms: -6.6 + 6.6 = 0.0 0.0 + X = -6.584831053 + 6.6 X = -6.584831053 + 6.6 Combine like terms: -6.584831053 + 6.6 = 0.015168947 X = 0.015168947 Simplifying X = 0.015168947Solution
