Simplifying x2 + -5 + 33 = 7x + -3 Reorder the terms: -5 + 33 + x2 = 7x + -3 Combine like terms: -5 + 33 = 28 28 + x2 = 7x + -3 Reorder the terms: 28 + x2 = -3 + 7x Solving 28 + x2 = -3 + 7x Solving for variable 'x'. Reorder the terms: 28 + 3 + -7x + x2 = -3 + 7x + 3 + -7x Combine like terms: 28 + 3 = 31 31 + -7x + x2 = -3 + 7x + 3 + -7x Reorder the terms: 31 + -7x + x2 = -3 + 3 + 7x + -7x Combine like terms: -3 + 3 = 0 31 + -7x + x2 = 0 + 7x + -7x 31 + -7x + x2 = 7x + -7x Combine like terms: 7x + -7x = 0 31 + -7x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-31' to each side of the equation. 31 + -7x + -31 + x2 = 0 + -31 Reorder the terms: 31 + -31 + -7x + x2 = 0 + -31 Combine like terms: 31 + -31 = 0 0 + -7x + x2 = 0 + -31 -7x + x2 = 0 + -31 Combine like terms: 0 + -31 = -31 -7x + x2 = -31 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 = -31 + 12.25 Reorder the terms: 12.25 + -7x + x2 = -31 + 12.25 Combine like terms: -31 + 12.25 = -18.75 12.25 + -7x + x2 = -18.75 Factor a perfect square on the left side: (x + -3.5)(x + -3.5) = -18.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
