Simplifying -1x2 + 4x = -51 Reorder the terms: 4x + -1x2 = -51 Solving 4x + -1x2 = -51 Solving for variable 'x'. Reorder the terms: 51 + 4x + -1x2 = -51 + 51 Combine like terms: -51 + 51 = 0 51 + 4x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -51 + -4x + x2 = 0 Move the constant term to the right: Add '51' to each side of the equation. -51 + -4x + 51 + x2 = 0 + 51 Reorder the terms: -51 + 51 + -4x + x2 = 0 + 51 Combine like terms: -51 + 51 = 0 0 + -4x + x2 = 0 + 51 -4x + x2 = 0 + 51 Combine like terms: 0 + 51 = 51 -4x + x2 = 51 The x term is -4x. Take half its coefficient (-2). Square it (4) and add it to both sides. Add '4' to each side of the equation. -4x + 4 + x2 = 51 + 4 Reorder the terms: 4 + -4x + x2 = 51 + 4 Combine like terms: 51 + 4 = 55 4 + -4x + x2 = 55 Factor a perfect square on the left side: (x + -2)(x + -2) = 55 Calculate the square root of the right side: 7.416198487 Break this problem into two subproblems by setting (x + -2) equal to 7.416198487 and -7.416198487.Subproblem 1
x + -2 = 7.416198487 Simplifying x + -2 = 7.416198487 Reorder the terms: -2 + x = 7.416198487 Solving -2 + x = 7.416198487 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + x = 7.416198487 + 2 Combine like terms: -2 + 2 = 0 0 + x = 7.416198487 + 2 x = 7.416198487 + 2 Combine like terms: 7.416198487 + 2 = 9.416198487 x = 9.416198487 Simplifying x = 9.416198487Subproblem 2
x + -2 = -7.416198487 Simplifying x + -2 = -7.416198487 Reorder the terms: -2 + x = -7.416198487 Solving -2 + x = -7.416198487 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + x = -7.416198487 + 2 Combine like terms: -2 + 2 = 0 0 + x = -7.416198487 + 2 x = -7.416198487 + 2 Combine like terms: -7.416198487 + 2 = -5.416198487 x = -5.416198487 Simplifying x = -5.416198487Solution
