Simplifying 0 = -4x2 + 7x + 4 Reorder the terms: 0 = 4 + 7x + -4x2 Solving 0 = 4 + 7x + -4x2 Solving for variable 'x'. Combine like terms: 0 + -4 = -4 -4 + -7x + 4x2 = 4 + 7x + -4x2 + -4 + -7x + 4x2 Reorder the terms: -4 + -7x + 4x2 = 4 + -4 + 7x + -7x + -4x2 + 4x2 Combine like terms: 4 + -4 = 0 -4 + -7x + 4x2 = 0 + 7x + -7x + -4x2 + 4x2 -4 + -7x + 4x2 = 7x + -7x + -4x2 + 4x2 Combine like terms: 7x + -7x = 0 -4 + -7x + 4x2 = 0 + -4x2 + 4x2 -4 + -7x + 4x2 = -4x2 + 4x2 Combine like terms: -4x2 + 4x2 = 0 -4 + -7x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -1 + -1.75x + x2 = 0 Move the constant term to the right: Add '1' to each side of the equation. -1 + -1.75x + 1 + x2 = 0 + 1 Reorder the terms: -1 + 1 + -1.75x + x2 = 0 + 1 Combine like terms: -1 + 1 = 0 0 + -1.75x + x2 = 0 + 1 -1.75x + x2 = 0 + 1 Combine like terms: 0 + 1 = 1 -1.75x + x2 = 1 The x term is -1.75x. Take half its coefficient (-0.875). Square it (0.765625) and add it to both sides. Add '0.765625' to each side of the equation. -1.75x + 0.765625 + x2 = 1 + 0.765625 Reorder the terms: 0.765625 + -1.75x + x2 = 1 + 0.765625 Combine like terms: 1 + 0.765625 = 1.765625 0.765625 + -1.75x + x2 = 1.765625 Factor a perfect square on the left side: (x + -0.875)(x + -0.875) = 1.765625 Calculate the square root of the right side: 1.328768227 Break this problem into two subproblems by setting (x + -0.875) equal to 1.328768227 and -1.328768227.Subproblem 1
x + -0.875 = 1.328768227 Simplifying x + -0.875 = 1.328768227 Reorder the terms: -0.875 + x = 1.328768227 Solving -0.875 + x = 1.328768227 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.875' to each side of the equation. -0.875 + 0.875 + x = 1.328768227 + 0.875 Combine like terms: -0.875 + 0.875 = 0.000 0.000 + x = 1.328768227 + 0.875 x = 1.328768227 + 0.875 Combine like terms: 1.328768227 + 0.875 = 2.203768227 x = 2.203768227 Simplifying x = 2.203768227Subproblem 2
x + -0.875 = -1.328768227 Simplifying x + -0.875 = -1.328768227 Reorder the terms: -0.875 + x = -1.328768227 Solving -0.875 + x = -1.328768227 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.875' to each side of the equation. -0.875 + 0.875 + x = -1.328768227 + 0.875 Combine like terms: -0.875 + 0.875 = 0.000 0.000 + x = -1.328768227 + 0.875 x = -1.328768227 + 0.875 Combine like terms: -1.328768227 + 0.875 = -0.453768227 x = -0.453768227 Simplifying x = -0.453768227Solution
