Simplifying x2 + 10x + 15 = 3x + -15 Reorder the terms: 15 + 10x + x2 = 3x + -15 Reorder the terms: 15 + 10x + x2 = -15 + 3x Solving 15 + 10x + x2 = -15 + 3x Solving for variable 'x'. Reorder the terms: 15 + 15 + 10x + -3x + x2 = -15 + 3x + 15 + -3x Combine like terms: 15 + 15 = 30 30 + 10x + -3x + x2 = -15 + 3x + 15 + -3x Combine like terms: 10x + -3x = 7x 30 + 7x + x2 = -15 + 3x + 15 + -3x Reorder the terms: 30 + 7x + x2 = -15 + 15 + 3x + -3x Combine like terms: -15 + 15 = 0 30 + 7x + x2 = 0 + 3x + -3x 30 + 7x + x2 = 3x + -3x Combine like terms: 3x + -3x = 0 30 + 7x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-30' to each side of the equation. 30 + 7x + -30 + x2 = 0 + -30 Reorder the terms: 30 + -30 + 7x + x2 = 0 + -30 Combine like terms: 30 + -30 = 0 0 + 7x + x2 = 0 + -30 7x + x2 = 0 + -30 Combine like terms: 0 + -30 = -30 7x + x2 = -30 The x term is 7x. Take half its coefficient (3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. 7x + 12.25 + x2 = -30 + 12.25 Reorder the terms: 12.25 + 7x + x2 = -30 + 12.25 Combine like terms: -30 + 12.25 = -17.75 12.25 + 7x + x2 = -17.75 Factor a perfect square on the left side: (x + 3.5)(x + 3.5) = -17.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
