Simplifying x2 + -30x + 54 = 50 Reorder the terms: 54 + -30x + x2 = 50 Solving 54 + -30x + x2 = 50 Solving for variable 'x'. Reorder the terms: 54 + -50 + -30x + x2 = 50 + -50 Combine like terms: 54 + -50 = 4 4 + -30x + x2 = 50 + -50 Combine like terms: 50 + -50 = 0 4 + -30x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-4' to each side of the equation. 4 + -30x + -4 + x2 = 0 + -4 Reorder the terms: 4 + -4 + -30x + x2 = 0 + -4 Combine like terms: 4 + -4 = 0 0 + -30x + x2 = 0 + -4 -30x + x2 = 0 + -4 Combine like terms: 0 + -4 = -4 -30x + x2 = -4 The x term is -30x. Take half its coefficient (-15). Square it (225) and add it to both sides. Add '225' to each side of the equation. -30x + 225 + x2 = -4 + 225 Reorder the terms: 225 + -30x + x2 = -4 + 225 Combine like terms: -4 + 225 = 221 225 + -30x + x2 = 221 Factor a perfect square on the left side: (x + -15)(x + -15) = 221 Calculate the square root of the right side: 14.866068747 Break this problem into two subproblems by setting (x + -15) equal to 14.866068747 and -14.866068747.Subproblem 1
