Simplifying (2x2 + 6x + 1) + (-7x2 + 2x + -3) = 0 Reorder the terms: (1 + 6x + 2x2) + (-7x2 + 2x + -3) = 0 Remove parenthesis around (1 + 6x + 2x2) 1 + 6x + 2x2 + (-7x2 + 2x + -3) = 0 Reorder the terms: 1 + 6x + 2x2 + (-3 + 2x + -7x2) = 0 Remove parenthesis around (-3 + 2x + -7x2) 1 + 6x + 2x2 + -3 + 2x + -7x2 = 0 Reorder the terms: 1 + -3 + 6x + 2x + 2x2 + -7x2 = 0 Combine like terms: 1 + -3 = -2 -2 + 6x + 2x + 2x2 + -7x2 = 0 Combine like terms: 6x + 2x = 8x -2 + 8x + 2x2 + -7x2 = 0 Combine like terms: 2x2 + -7x2 = -5x2 -2 + 8x + -5x2 = 0 Solving -2 + 8x + -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'. 0.4 + -1.6x + x2 = 0 Move the constant term to the right: Add '-0.4' to each side of the equation. 0.4 + -1.6x + -0.4 + x2 = 0 + -0.4 Reorder the terms: 0.4 + -0.4 + -1.6x + x2 = 0 + -0.4 Combine like terms: 0.4 + -0.4 = 0.0 0.0 + -1.6x + x2 = 0 + -0.4 -1.6x + x2 = 0 + -0.4 Combine like terms: 0 + -0.4 = -0.4 -1.6x + x2 = -0.4 The x term is -1.6x. Take half its coefficient (-0.8). Square it (0.64) and add it to both sides. Add '0.64' to each side of the equation. -1.6x + 0.64 + x2 = -0.4 + 0.64 Reorder the terms: 0.64 + -1.6x + x2 = -0.4 + 0.64 Combine like terms: -0.4 + 0.64 = 0.24 0.64 + -1.6x + x2 = 0.24 Factor a perfect square on the left side: (x + -0.8)(x + -0.8) = 0.24 Calculate the square root of the right side: 0.489897949 Break this problem into two subproblems by setting (x + -0.8) equal to 0.489897949 and -0.489897949.Subproblem 1
x + -0.8 = 0.489897949 Simplifying x + -0.8 = 0.489897949 Reorder the terms: -0.8 + x = 0.489897949 Solving -0.8 + x = 0.489897949 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.8' to each side of the equation. -0.8 + 0.8 + x = 0.489897949 + 0.8 Combine like terms: -0.8 + 0.8 = 0.0 0.0 + x = 0.489897949 + 0.8 x = 0.489897949 + 0.8 Combine like terms: 0.489897949 + 0.8 = 1.289897949 x = 1.289897949 Simplifying x = 1.289897949Subproblem 2
x + -0.8 = -0.489897949 Simplifying x + -0.8 = -0.489897949 Reorder the terms: -0.8 + x = -0.489897949 Solving -0.8 + x = -0.489897949 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.8' to each side of the equation. -0.8 + 0.8 + x = -0.489897949 + 0.8 Combine like terms: -0.8 + 0.8 = 0.0 0.0 + x = -0.489897949 + 0.8 x = -0.489897949 + 0.8 Combine like terms: -0.489897949 + 0.8 = 0.310102051 x = 0.310102051 Simplifying x = 0.310102051Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.289897949, 0.310102051}
