Simplifying X2 + 7X + 10 = 140 Reorder the terms: 10 + 7X + X2 = 140 Solving 10 + 7X + X2 = 140 Solving for variable 'X'. Reorder the terms: 10 + -140 + 7X + X2 = 140 + -140 Combine like terms: 10 + -140 = -130 -130 + 7X + X2 = 140 + -140 Combine like terms: 140 + -140 = 0 -130 + 7X + X2 = 0 Begin completing the square. Move the constant term to the right: Add '130' to each side of the equation. -130 + 7X + 130 + X2 = 0 + 130 Reorder the terms: -130 + 130 + 7X + X2 = 0 + 130 Combine like terms: -130 + 130 = 0 0 + 7X + X2 = 0 + 130 7X + X2 = 0 + 130 Combine like terms: 0 + 130 = 130 7X + X2 = 130 The X term is 7X. Take half its coefficient (3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. 7X + 12.25 + X2 = 130 + 12.25 Reorder the terms: 12.25 + 7X + X2 = 130 + 12.25 Combine like terms: 130 + 12.25 = 142.25 12.25 + 7X + X2 = 142.25 Factor a perfect square on the left side: (X + 3.5)(X + 3.5) = 142.25 Calculate the square root of the right side: 11.926860442 Break this problem into two subproblems by setting (X + 3.5) equal to 11.926860442 and -11.926860442.Subproblem 1
X + 3.5 = 11.926860442 Simplifying X + 3.5 = 11.926860442 Reorder the terms: 3.5 + X = 11.926860442 Solving 3.5 + X = 11.926860442 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '-3.5' to each side of the equation. 3.5 + -3.5 + X = 11.926860442 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + X = 11.926860442 + -3.5 X = 11.926860442 + -3.5 Combine like terms: 11.926860442 + -3.5 = 8.426860442 X = 8.426860442 Simplifying X = 8.426860442Subproblem 2
X + 3.5 = -11.926860442 Simplifying X + 3.5 = -11.926860442 Reorder the terms: 3.5 + X = -11.926860442 Solving 3.5 + X = -11.926860442 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '-3.5' to each side of the equation. 3.5 + -3.5 + X = -11.926860442 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + X = -11.926860442 + -3.5 X = -11.926860442 + -3.5 Combine like terms: -11.926860442 + -3.5 = -15.426860442 X = -15.426860442 Simplifying X = -15.426860442Solution
The solution to the problem is based on the solutions from the subproblems. X = {8.426860442, -15.426860442}
