Simplifying 0 = x2 + -21x + 48 Reorder the terms: 0 = 48 + -21x + x2 Solving 0 = 48 + -21x + x2 Solving for variable 'x'. Combine like terms: 0 + -48 = -48 -48 + 21x + -1x2 = 48 + -21x + x2 + -48 + 21x + -1x2 Reorder the terms: -48 + 21x + -1x2 = 48 + -48 + -21x + 21x + x2 + -1x2 Combine like terms: 48 + -48 = 0 -48 + 21x + -1x2 = 0 + -21x + 21x + x2 + -1x2 -48 + 21x + -1x2 = -21x + 21x + x2 + -1x2 Combine like terms: -21x + 21x = 0 -48 + 21x + -1x2 = 0 + x2 + -1x2 -48 + 21x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 -48 + 21x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 48 + -21x + x2 = 0 Move the constant term to the right: Add '-48' to each side of the equation. 48 + -21x + -48 + x2 = 0 + -48 Reorder the terms: 48 + -48 + -21x + x2 = 0 + -48 Combine like terms: 48 + -48 = 0 0 + -21x + x2 = 0 + -48 -21x + x2 = 0 + -48 Combine like terms: 0 + -48 = -48 -21x + x2 = -48 The x term is -21x. Take half its coefficient (-10.5). Square it (110.25) and add it to both sides. Add '110.25' to each side of the equation. -21x + 110.25 + x2 = -48 + 110.25 Reorder the terms: 110.25 + -21x + x2 = -48 + 110.25 Combine like terms: -48 + 110.25 = 62.25 110.25 + -21x + x2 = 62.25 Factor a perfect square on the left side: (x + -10.5)(x + -10.5) = 62.25 Calculate the square root of the right side: 7.889866919 Break this problem into two subproblems by setting (x + -10.5) equal to 7.889866919 and -7.889866919.Subproblem 1
x + -10.5 = 7.889866919 Simplifying x + -10.5 = 7.889866919 Reorder the terms: -10.5 + x = 7.889866919 Solving -10.5 + x = 7.889866919 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '10.5' to each side of the equation. -10.5 + 10.5 + x = 7.889866919 + 10.5 Combine like terms: -10.5 + 10.5 = 0.0 0.0 + x = 7.889866919 + 10.5 x = 7.889866919 + 10.5 Combine like terms: 7.889866919 + 10.5 = 18.389866919 x = 18.389866919 Simplifying x = 18.389866919Subproblem 2
x + -10.5 = -7.889866919 Simplifying x + -10.5 = -7.889866919 Reorder the terms: -10.5 + x = -7.889866919 Solving -10.5 + x = -7.889866919 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '10.5' to each side of the equation. -10.5 + 10.5 + x = -7.889866919 + 10.5 Combine like terms: -10.5 + 10.5 = 0.0 0.0 + x = -7.889866919 + 10.5 x = -7.889866919 + 10.5 Combine like terms: -7.889866919 + 10.5 = 2.610133081 x = 2.610133081 Simplifying x = 2.610133081Solution
