Simplifying (2x2 + -4x + 8) + -1(3x2 + 10x + 2) = 0 Reorder the terms: (8 + -4x + 2x2) + -1(3x2 + 10x + 2) = 0 Remove parenthesis around (8 + -4x + 2x2) 8 + -4x + 2x2 + -1(3x2 + 10x + 2) = 0 Reorder the terms: 8 + -4x + 2x2 + -1(2 + 10x + 3x2) = 0 8 + -4x + 2x2 + (2 * -1 + 10x * -1 + 3x2 * -1) = 0 8 + -4x + 2x2 + (-2 + -10x + -3x2) = 0 Reorder the terms: 8 + -2 + -4x + -10x + 2x2 + -3x2 = 0 Combine like terms: 8 + -2 = 6 6 + -4x + -10x + 2x2 + -3x2 = 0 Combine like terms: -4x + -10x = -14x 6 + -14x + 2x2 + -3x2 = 0 Combine like terms: 2x2 + -3x2 = -1x2 6 + -14x + -1x2 = 0 Solving 6 + -14x + -1x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -6 + 14x + x2 = 0 Move the constant term to the right: Add '6' to each side of the equation. -6 + 14x + 6 + x2 = 0 + 6 Reorder the terms: -6 + 6 + 14x + x2 = 0 + 6 Combine like terms: -6 + 6 = 0 0 + 14x + x2 = 0 + 6 14x + x2 = 0 + 6 Combine like terms: 0 + 6 = 6 14x + x2 = 6 The x term is 14x. Take half its coefficient (7). Square it (49) and add it to both sides. Add '49' to each side of the equation. 14x + 49 + x2 = 6 + 49 Reorder the terms: 49 + 14x + x2 = 6 + 49 Combine like terms: 6 + 49 = 55 49 + 14x + x2 = 55 Factor a perfect square on the left side: (x + 7)(x + 7) = 55 Calculate the square root of the right side: 7.416198487 Break this problem into two subproblems by setting (x + 7) equal to 7.416198487 and -7.416198487.Subproblem 1
x + 7 = 7.416198487 Simplifying x + 7 = 7.416198487 Reorder the terms: 7 + x = 7.416198487 Solving 7 + x = 7.416198487 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + x = 7.416198487 + -7 Combine like terms: 7 + -7 = 0 0 + x = 7.416198487 + -7 x = 7.416198487 + -7 Combine like terms: 7.416198487 + -7 = 0.416198487 x = 0.416198487 Simplifying x = 0.416198487Subproblem 2
x + 7 = -7.416198487 Simplifying x + 7 = -7.416198487 Reorder the terms: 7 + x = -7.416198487 Solving 7 + x = -7.416198487 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + x = -7.416198487 + -7 Combine like terms: 7 + -7 = 0 0 + x = -7.416198487 + -7 x = -7.416198487 + -7 Combine like terms: -7.416198487 + -7 = -14.416198487 x = -14.416198487 Simplifying x = -14.416198487Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.416198487, -14.416198487}
