Simplifying -5X2 + -11X + 8 = 0 Reorder the terms: 8 + -11X + -5X2 = 0 Solving 8 + -11X + -5X2 = 0 Solving for variable 'X'. Begin completing the square. Divide all terms by -5 the coefficient of the squared term: Divide each side by '-5'. -1.6 + 2.2X + X2 = 0 Move the constant term to the right: Add '1.6' to each side of the equation. -1.6 + 2.2X + 1.6 + X2 = 0 + 1.6 Reorder the terms: -1.6 + 1.6 + 2.2X + X2 = 0 + 1.6 Combine like terms: -1.6 + 1.6 = 0.0 0.0 + 2.2X + X2 = 0 + 1.6 2.2X + X2 = 0 + 1.6 Combine like terms: 0 + 1.6 = 1.6 2.2X + X2 = 1.6 The X term is 2.2X. Take half its coefficient (1.1). Square it (1.21) and add it to both sides. Add '1.21' to each side of the equation. 2.2X + 1.21 + X2 = 1.6 + 1.21 Reorder the terms: 1.21 + 2.2X + X2 = 1.6 + 1.21 Combine like terms: 1.6 + 1.21 = 2.81 1.21 + 2.2X + X2 = 2.81 Factor a perfect square on the left side: (X + 1.1)(X + 1.1) = 2.81 Calculate the square root of the right side: 1.676305461 Break this problem into two subproblems by setting (X + 1.1) equal to 1.676305461 and -1.676305461.Subproblem 1
X + 1.1 = 1.676305461 Simplifying X + 1.1 = 1.676305461 Reorder the terms: 1.1 + X = 1.676305461 Solving 1.1 + X = 1.676305461 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '-1.1' to each side of the equation. 1.1 + -1.1 + X = 1.676305461 + -1.1 Combine like terms: 1.1 + -1.1 = 0.0 0.0 + X = 1.676305461 + -1.1 X = 1.676305461 + -1.1 Combine like terms: 1.676305461 + -1.1 = 0.576305461 X = 0.576305461 Simplifying X = 0.576305461Subproblem 2
X + 1.1 = -1.676305461 Simplifying X + 1.1 = -1.676305461 Reorder the terms: 1.1 + X = -1.676305461 Solving 1.1 + X = -1.676305461 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '-1.1' to each side of the equation. 1.1 + -1.1 + X = -1.676305461 + -1.1 Combine like terms: 1.1 + -1.1 = 0.0 0.0 + X = -1.676305461 + -1.1 X = -1.676305461 + -1.1 Combine like terms: -1.676305461 + -1.1 = -2.776305461 X = -2.776305461 Simplifying X = -2.776305461Solution
The solution to the problem is based on the solutions from the subproblems. X = {0.576305461, -2.776305461}
