Simplifying 20f2 + -21f + -4 = 0 Reorder the terms: -4 + -21f + 20f2 = 0 Solving -4 + -21f + 20f2 = 0 Solving for variable 'f'. Begin completing the square. Divide all terms by 20 the coefficient of the squared term: Divide each side by '20'. -0.2 + -1.05f + f2 = 0 Move the constant term to the right: Add '0.2' to each side of the equation. -0.2 + -1.05f + 0.2 + f2 = 0 + 0.2 Reorder the terms: -0.2 + 0.2 + -1.05f + f2 = 0 + 0.2 Combine like terms: -0.2 + 0.2 = 0.0 0.0 + -1.05f + f2 = 0 + 0.2 -1.05f + f2 = 0 + 0.2 Combine like terms: 0 + 0.2 = 0.2 -1.05f + f2 = 0.2 The f term is -1.05f. Take half its coefficient (-0.525). Square it (0.275625) and add it to both sides. Add '0.275625' to each side of the equation. -1.05f + 0.275625 + f2 = 0.2 + 0.275625 Reorder the terms: 0.275625 + -1.05f + f2 = 0.2 + 0.275625 Combine like terms: 0.2 + 0.275625 = 0.475625 0.275625 + -1.05f + f2 = 0.475625 Factor a perfect square on the left side: (f + -0.525)(f + -0.525) = 0.475625 Calculate the square root of the right side: 0.689655711 Break this problem into two subproblems by setting (f + -0.525) equal to 0.689655711 and -0.689655711.Subproblem 1
f + -0.525 = 0.689655711 Simplifying f + -0.525 = 0.689655711 Reorder the terms: -0.525 + f = 0.689655711 Solving -0.525 + f = 0.689655711 Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Add '0.525' to each side of the equation. -0.525 + 0.525 + f = 0.689655711 + 0.525 Combine like terms: -0.525 + 0.525 = 0.000 0.000 + f = 0.689655711 + 0.525 f = 0.689655711 + 0.525 Combine like terms: 0.689655711 + 0.525 = 1.214655711 f = 1.214655711 Simplifying f = 1.214655711Subproblem 2
f + -0.525 = -0.689655711 Simplifying f + -0.525 = -0.689655711 Reorder the terms: -0.525 + f = -0.689655711 Solving -0.525 + f = -0.689655711 Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Add '0.525' to each side of the equation. -0.525 + 0.525 + f = -0.689655711 + 0.525 Combine like terms: -0.525 + 0.525 = 0.000 0.000 + f = -0.689655711 + 0.525 f = -0.689655711 + 0.525 Combine like terms: -0.689655711 + 0.525 = -0.164655711 f = -0.164655711 Simplifying f = -0.164655711Solution
