Simplifying x2 + -10x = 3 Reorder the terms: -10x + x2 = 3 Solving -10x + x2 = 3 Solving for variable 'x'. Reorder the terms: -3 + -10x + x2 = 3 + -3 Combine like terms: 3 + -3 = 0 -3 + -10x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '3' to each side of the equation. -3 + -10x + 3 + x2 = 0 + 3 Reorder the terms: -3 + 3 + -10x + x2 = 0 + 3 Combine like terms: -3 + 3 = 0 0 + -10x + x2 = 0 + 3 -10x + x2 = 0 + 3 Combine like terms: 0 + 3 = 3 -10x + x2 = 3 The x term is -10x. Take half its coefficient (-5). Square it (25) and add it to both sides. Add '25' to each side of the equation. -10x + 25 + x2 = 3 + 25 Reorder the terms: 25 + -10x + x2 = 3 + 25 Combine like terms: 3 + 25 = 28 25 + -10x + x2 = 28 Factor a perfect square on the left side: (x + -5)(x + -5) = 28 Calculate the square root of the right side: 5.291502622 Break this problem into two subproblems by setting (x + -5) equal to 5.291502622 and -5.291502622.Subproblem 1
x + -5 = 5.291502622 Simplifying x + -5 = 5.291502622 Reorder the terms: -5 + x = 5.291502622 Solving -5 + x = 5.291502622 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right.
