Simplifying 20x2 + 79x + -45 = 0 Reorder the terms: -45 + 79x + 20x2 = 0 Solving -45 + 79x + 20x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 20 the coefficient of the squared term: Divide each side by '20'. -2.25 + 3.95x + x2 = 0 Move the constant term to the right: Add '2.25' to each side of the equation. -2.25 + 3.95x + 2.25 + x2 = 0 + 2.25 Reorder the terms: -2.25 + 2.25 + 3.95x + x2 = 0 + 2.25 Combine like terms: -2.25 + 2.25 = 0.00 0.00 + 3.95x + x2 = 0 + 2.25 3.95x + x2 = 0 + 2.25 Combine like terms: 0 + 2.25 = 2.25 3.95x + x2 = 2.25 The x term is 3.95x. Take half its coefficient (1.975). Square it (3.900625) and add it to both sides. Add '3.900625' to each side of the equation. 3.95x + 3.900625 + x2 = 2.25 + 3.900625 Reorder the terms: 3.900625 + 3.95x + x2 = 2.25 + 3.900625 Combine like terms: 2.25 + 3.900625 = 6.150625 3.900625 + 3.95x + x2 = 6.150625 Factor a perfect square on the left side: (x + 1.975)(x + 1.975) = 6.150625 Calculate the square root of the right side: 2.480045362 Break this problem into two subproblems by setting (x + 1.975) equal to 2.480045362 and -2.480045362.Subproblem 1
x + 1.975 = 2.480045362 Simplifying x + 1.975 = 2.480045362 Reorder the terms: 1.975 + x = 2.480045362 Solving 1.975 + x = 2.480045362 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.975' to each side of the equation. 1.975 + -1.975 + x = 2.480045362 + -1.975 Combine like terms: 1.975 + -1.975 = 0.000 0.000 + x = 2.480045362 + -1.975 x = 2.480045362 + -1.975 Combine like terms: 2.480045362 + -1.975 = 0.505045362 x = 0.505045362 Simplifying x = 0.505045362Subproblem 2
x + 1.975 = -2.480045362 Simplifying x + 1.975 = -2.480045362 Reorder the terms: 1.975 + x = -2.480045362 Solving 1.975 + x = -2.480045362 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.975' to each side of the equation. 1.975 + -1.975 + x = -2.480045362 + -1.975 Combine like terms: 1.975 + -1.975 = 0.000 0.000 + x = -2.480045362 + -1.975 x = -2.480045362 + -1.975 Combine like terms: -2.480045362 + -1.975 = -4.455045362 x = -4.455045362 Simplifying x = -4.455045362Solution
