Simplifying 8x2 + 36x + 36 = 25 Reorder the terms: 36 + 36x + 8x2 = 25 Solving 36 + 36x + 8x2 = 25 Solving for variable 'x'. Reorder the terms: 36 + -25 + 36x + 8x2 = 25 + -25 Combine like terms: 36 + -25 = 11 11 + 36x + 8x2 = 25 + -25 Combine like terms: 25 + -25 = 0 11 + 36x + 8x2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. 1.375 + 4.5x + x2 = 0 Move the constant term to the right: Add '-1.375' to each side of the equation. 1.375 + 4.5x + -1.375 + x2 = 0 + -1.375 Reorder the terms: 1.375 + -1.375 + 4.5x + x2 = 0 + -1.375 Combine like terms: 1.375 + -1.375 = 0.000 0.000 + 4.5x + x2 = 0 + -1.375 4.5x + x2 = 0 + -1.375 Combine like terms: 0 + -1.375 = -1.375 4.5x + x2 = -1.375 The x term is 4.5x. Take half its coefficient (2.25). Square it (5.0625) and add it to both sides. Add '5.0625' to each side of the equation. 4.5x + 5.0625 + x2 = -1.375 + 5.0625 Reorder the terms: 5.0625 + 4.5x + x2 = -1.375 + 5.0625 Combine like terms: -1.375 + 5.0625 = 3.6875 5.0625 + 4.5x + x2 = 3.6875 Factor a perfect square on the left side: (x + 2.25)(x + 2.25) = 3.6875 Calculate the square root of the right side: 1.920286437 Break this problem into two subproblems by setting (x + 2.25) equal to 1.920286437 and -1.920286437.Subproblem 1
