Simplifying 16x2 + 18x = 19 Reorder the terms: 18x + 16x2 = 19 Solving 18x + 16x2 = 19 Solving for variable 'x'. Reorder the terms: -19 + 18x + 16x2 = 19 + -19 Combine like terms: 19 + -19 = 0 -19 + 18x + 16x2 = 0 Begin completing the square. Divide all terms by 16 the coefficient of the squared term: Divide each side by '16'. -1.1875 + 1.125x + x2 = 0 Move the constant term to the right: Add '1.1875' to each side of the equation. -1.1875 + 1.125x + 1.1875 + x2 = 0 + 1.1875 Reorder the terms: -1.1875 + 1.1875 + 1.125x + x2 = 0 + 1.1875 Combine like terms: -1.1875 + 1.1875 = 0.0000 0.0000 + 1.125x + x2 = 0 + 1.1875 1.125x + x2 = 0 + 1.1875 Combine like terms: 0 + 1.1875 = 1.1875 1.125x + x2 = 1.1875 The x term is 1.125x. Take half its coefficient (0.5625). Square it (0.31640625) and add it to both sides. Add '0.31640625' to each side of the equation. 1.125x + 0.31640625 + x2 = 1.1875 + 0.31640625 Reorder the terms: 0.31640625 + 1.125x + x2 = 1.1875 + 0.31640625 Combine like terms: 1.1875 + 0.31640625 = 1.50390625 0.31640625 + 1.125x + x2 = 1.50390625 Factor a perfect square on the left side: (x + 0.5625)(x + 0.5625) = 1.50390625 Calculate the square root of the right side: 1.226338554 Break this problem into two subproblems by setting (x + 0.5625) equal to 1.226338554 and -1.226338554.Subproblem 1
x + 0.5625 = 1.226338554 Simplifying x + 0.5625 = 1.226338554 Reorder the terms: 0.5625 + x = 1.226338554 Solving 0.5625 + x = 1.226338554 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5625' to each side of the equation. 0.5625 + -0.5625 + x = 1.226338554 + -0.5625 Combine like terms: 0.5625 + -0.5625 = 0.0000 0.0000 + x = 1.226338554 + -0.5625 x = 1.226338554 + -0.5625 Combine like terms: 1.226338554 + -0.5625 = 0.663838554 x = 0.663838554 Simplifying x = 0.663838554Subproblem 2
x + 0.5625 = -1.226338554 Simplifying x + 0.5625 = -1.226338554 Reorder the terms: 0.5625 + x = -1.226338554 Solving 0.5625 + x = -1.226338554 Solving for variable 'x'.
