Simplifying x2 + -35x + 490 = 0 Reorder the terms: 490 + -35x + x2 = 0 Solving 490 + -35x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-490' to each side of the equation. 490 + -35x + -490 + x2 = 0 + -490 Reorder the terms: 490 + -490 + -35x + x2 = 0 + -490 Combine like terms: 490 + -490 = 0 0 + -35x + x2 = 0 + -490 -35x + x2 = 0 + -490 Combine like terms: 0 + -490 = -490 -35x + x2 = -490 The x term is -35x. Take half its coefficient (-17.5). Square it (306.25) and add it to both sides. Add '306.25' to each side of the equation. -35x + 306.25 + x2 = -490 + 306.25 Reorder the terms: 306.25 + -35x + x2 = -490 + 306.25 Combine like terms: -490 + 306.25 = -183.75 306.25 + -35x + x2 = -183.75 Factor a perfect square on the left side: (x + -17.5)(x + -17.5) = -183.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
