Simplifying X2 + 5X = 315 Reorder the terms: 5X + X2 = 315 Solving 5X + X2 = 315 Solving for variable 'X'. Reorder the terms: -315 + 5X + X2 = 315 + -315 Combine like terms: 315 + -315 = 0 -315 + 5X + X2 = 0 Begin completing the square. Move the constant term to the right: Add '315' to each side of the equation. -315 + 5X + 315 + X2 = 0 + 315 Reorder the terms: -315 + 315 + 5X + X2 = 0 + 315 Combine like terms: -315 + 315 = 0 0 + 5X + X2 = 0 + 315 5X + X2 = 0 + 315 Combine like terms: 0 + 315 = 315 5X + X2 = 315 The X term is 5X. Take half its coefficient (2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. 5X + 6.25 + X2 = 315 + 6.25 Reorder the terms: 6.25 + 5X + X2 = 315 + 6.25 Combine like terms: 315 + 6.25 = 321.25 6.25 + 5X + X2 = 321.25 Factor a perfect square on the left side: (X + 2.5)(X + 2.5) = 321.25 Calculate the square root of the right side: 17.923448329 Break this problem into two subproblems by setting (X + 2.5) equal to 17.923448329 and -17.923448329.Subproblem 1
X + 2.5 = 17.923448329 Simplifying X + 2.5 = 17.923448329 Reorder the terms: 2.5 + X = 17.923448329 Solving 2.5 + X = 17.923448329 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '-2.5' to each side of the equation. 2.5 + -2.5 + X = 17.923448329 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + X = 17.923448329 + -2.5 X = 17.923448329 + -2.5 Combine like terms: 17.923448329 + -2.5 = 15.423448329 X = 15.423448329 Simplifying X = 15.423448329Subproblem 2
X + 2.5 = -17.923448329 Simplifying X + 2.5 = -17.923448329 Reorder the terms: 2.5 + X = -17.923448329 Solving 2.5 + X = -17.923448329 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '-2.5' to each side of the equation. 2.5 + -2.5 + X = -17.923448329 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + X = -17.923448329 + -2.5 X = -17.923448329 + -2.5 Combine like terms: -17.923448329 + -2.5 = -20.423448329 X = -20.423448329 Simplifying X = -20.423448329Solution
