Simplifying x2 + 49x + 630 = 0 Reorder the terms: 630 + 49x + x2 = 0 Solving 630 + 49x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-630' to each side of the equation. 630 + 49x + -630 + x2 = 0 + -630 Reorder the terms: 630 + -630 + 49x + x2 = 0 + -630 Combine like terms: 630 + -630 = 0 0 + 49x + x2 = 0 + -630 49x + x2 = 0 + -630 Combine like terms: 0 + -630 = -630 49x + x2 = -630 The x term is 49x. Take half its coefficient (24.5). Square it (600.25) and add it to both sides. Add '600.25' to each side of the equation. 49x + 600.25 + x2 = -630 + 600.25 Reorder the terms: 600.25 + 49x + x2 = -630 + 600.25 Combine like terms: -630 + 600.25 = -29.75 600.25 + 49x + x2 = -29.75 Factor a perfect square on the left side: (x + 24.5)(x + 24.5) = -29.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
