Simplifying x2 + 2x + 70 = 0 Reorder the terms: 70 + 2x + x2 = 0 Solving 70 + 2x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-70' to each side of the equation. 70 + 2x + -70 + x2 = 0 + -70 Reorder the terms: 70 + -70 + 2x + x2 = 0 + -70 Combine like terms: 70 + -70 = 0 0 + 2x + x2 = 0 + -70 2x + x2 = 0 + -70 Combine like terms: 0 + -70 = -70 2x + x2 = -70 The x term is 2x. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2x + 1 + x2 = -70 + 1 Reorder the terms: 1 + 2x + x2 = -70 + 1 Combine like terms: -70 + 1 = -69 1 + 2x + x2 = -69 Factor a perfect square on the left side: (x + 1)(x + 1) = -69 Can't calculate square root of the right side. The solution to this equation could not be determined.
