Simplifying x(3x + 19) = 27 Reorder the terms: x(19 + 3x) = 27 (19 * x + 3x * x) = 27 (19x + 3x2) = 27 Solving 19x + 3x2 = 27 Solving for variable 'x'. Reorder the terms: -27 + 19x + 3x2 = 27 + -27 Combine like terms: 27 + -27 = 0 -27 + 19x + 3x2 = 0 Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. -9 + 6.333333333x + x2 = 0 Move the constant term to the right: Add '9' to each side of the equation. -9 + 6.333333333x + 9 + x2 = 0 + 9 Reorder the terms: -9 + 9 + 6.333333333x + x2 = 0 + 9 Combine like terms: -9 + 9 = 0 0 + 6.333333333x + x2 = 0 + 9 6.333333333x + x2 = 0 + 9 Combine like terms: 0 + 9 = 9 6.333333333x + x2 = 9 The x term is 6.333333333x. Take half its coefficient (3.166666667). Square it (10.02777778) and add it to both sides. Add '10.02777778' to each side of the equation. 6.333333333x + 10.02777778 + x2 = 9 + 10.02777778 Reorder the terms: 10.02777778 + 6.333333333x + x2 = 9 + 10.02777778 Combine like terms: 9 + 10.02777778 = 19.02777778 10.02777778 + 6.333333333x + x2 = 19.02777778 Factor a perfect square on the left side: (x + 3.166666667)(x + 3.166666667) = 19.02777778 Calculate the square root of the right side: 4.36208411 Break this problem into two subproblems by setting (x + 3.166666667) equal to 4.36208411 and -4.36208411.Subproblem 1
