Simplifying 5x2 + -7x + -4 = 0 Reorder the terms: -4 + -7x + 5x2 = 0 Solving -4 + -7x + 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'. -0.8 + -1.4x + x2 = 0 Move the constant term to the right: Add '0.8' to each side of the equation. -0.8 + -1.4x + 0.8 + x2 = 0 + 0.8 Reorder the terms: -0.8 + 0.8 + -1.4x + x2 = 0 + 0.8 Combine like terms: -0.8 + 0.8 = 0.0 0.0 + -1.4x + x2 = 0 + 0.8 -1.4x + x2 = 0 + 0.8 Combine like terms: 0 + 0.8 = 0.8 -1.4x + x2 = 0.8 The x term is -1.4x. Take half its coefficient (-0.7). Square it (0.49) and add it to both sides. Add '0.49' to each side of the equation. -1.4x + 0.49 + x2 = 0.8 + 0.49 Reorder the terms: 0.49 + -1.4x + x2 = 0.8 + 0.49 Combine like terms: 0.8 + 0.49 = 1.29 0.49 + -1.4x + x2 = 1.29 Factor a perfect square on the left side: (x + -0.7)(x + -0.7) = 1.29 Calculate the square root of the right side: 1.135781669 Break this problem into two subproblems by setting (x + -0.7) equal to 1.135781669 and -1.135781669.Subproblem 1
x + -0.7 = 1.135781669 Simplifying x + -0.7 = 1.135781669 Reorder the terms: -0.7 + x = 1.135781669 Solving -0.7 + x = 1.135781669 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.7' to each side of the equation. -0.7 + 0.7 + x = 1.135781669 + 0.7 Combine like terms: -0.7 + 0.7 = 0.0 0.0 + x = 1.135781669 + 0.7 x = 1.135781669 + 0.7 Combine like terms: 1.135781669 + 0.7 = 1.835781669 x = 1.835781669 Simplifying x = 1.835781669Subproblem 2
x + -0.7 = -1.135781669 Simplifying x + -0.7 = -1.135781669 Reorder the terms: -0.7 + x = -1.135781669 Solving -0.7 + x = -1.135781669 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.7' to each side of the equation. -0.7 + 0.7 + x = -1.135781669 + 0.7 Combine like terms: -0.7 + 0.7 = 0.0 0.0 + x = -1.135781669 + 0.7 x = -1.135781669 + 0.7 Combine like terms: -1.135781669 + 0.7 = -0.435781669 x = -0.435781669 Simplifying x = -0.435781669Solution
