Simplifying X2 + X + -783 = 0 Reorder the terms: -783 + X + X2 = 0 Solving -783 + X + X2 = 0 Solving for variable 'X'. Begin completing the square. Move the constant term to the right: Add '783' to each side of the equation. -783 + X + 783 + X2 = 0 + 783 Reorder the terms: -783 + 783 + X + X2 = 0 + 783 Combine like terms: -783 + 783 = 0 0 + X + X2 = 0 + 783 X + X2 = 0 + 783 Combine like terms: 0 + 783 = 783 X + X2 = 783 The X term is X. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. X + 0.25 + X2 = 783 + 0.25 Reorder the terms: 0.25 + X + X2 = 783 + 0.25 Combine like terms: 783 + 0.25 = 783.25 0.25 + X + X2 = 783.25 Factor a perfect square on the left side: (X + 0.5)(X + 0.5) = 783.25 Calculate the square root of the right side: 27.986603938 Break this problem into two subproblems by setting (X + 0.5) equal to 27.986603938 and -27.986603938.Subproblem 1
X + 0.5 = 27.986603938 Simplifying X + 0.5 = 27.986603938 Reorder the terms: 0.5 + X = 27.986603938 Solving 0.5 + X = 27.986603938 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + X = 27.986603938 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + X = 27.986603938 + -0.5 X = 27.986603938 + -0.5 Combine like terms: 27.986603938 + -0.5 = 27.486603938 X = 27.486603938 Simplifying X = 27.486603938Subproblem 2
X + 0.5 = -27.986603938 Simplifying X + 0.5 = -27.986603938 Reorder the terms: 0.5 + X = -27.986603938 Solving 0.5 + X = -27.986603938 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + X = -27.986603938 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + X = -27.986603938 + -0.5 X = -27.986603938 + -0.5 Combine like terms: -27.986603938 + -0.5 = -28.486603938 X = -28.486603938 Simplifying X = -28.486603938Solution
