Simplifying 2X + -15 = -3X2 Reorder the terms: -15 + 2X = -3X2 Solving -15 + 2X = -3X2 Solving for variable 'X'. Combine like terms: -3X2 + 3X2 = 0 -15 + 2X + 3X2 = 0 Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. -5 + 0.6666666667X + X2 = 0 Move the constant term to the right: Add '5' to each side of the equation. -5 + 0.6666666667X + 5 + X2 = 0 + 5 Reorder the terms: -5 + 5 + 0.6666666667X + X2 = 0 + 5 Combine like terms: -5 + 5 = 0 0 + 0.6666666667X + X2 = 0 + 5 0.6666666667X + X2 = 0 + 5 Combine like terms: 0 + 5 = 5 0.6666666667X + X2 = 5 The X term is 0.6666666667X. Take half its coefficient (0.3333333334). Square it (0.1111111112) and add it to both sides. Add '0.1111111112' to each side of the equation. 0.6666666667X + 0.1111111112 + X2 = 5 + 0.1111111112 Reorder the terms: 0.1111111112 + 0.6666666667X + X2 = 5 + 0.1111111112 Combine like terms: 5 + 0.1111111112 = 5.1111111112 0.1111111112 + 0.6666666667X + X2 = 5.1111111112 Factor a perfect square on the left side: (X + 0.3333333334)(X + 0.3333333334) = 5.1111111112 Calculate the square root of the right side: 2.260776661 Break this problem into two subproblems by setting (X + 0.3333333334) equal to 2.260776661 and -2.260776661.Subproblem 1
X + 0.3333333334 = 2.260776661 Simplifying X + 0.3333333334 = 2.260776661 Reorder the terms: 0.3333333334 + X = 2.260776661 Solving 0.3333333334 + X = 2.260776661 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '-0.3333333334' to each side of the equation. 0.3333333334 + -0.3333333334 + X = 2.260776661 + -0.3333333334 Combine like terms: 0.3333333334 + -0.3333333334 = 0.0000000000 0.0000000000 + X = 2.260776661 + -0.3333333334 X = 2.260776661 + -0.3333333334 Combine like terms: 2.260776661 + -0.3333333334 = 1.9274433276 X = 1.9274433276 Simplifying X = 1.9274433276Subproblem 2
