Simplifying (x2 + 88) = 2x + 3 Reorder the terms: (88 + x2) = 2x + 3 Remove parenthesis around (88 + x2) 88 + x2 = 2x + 3 Reorder the terms: 88 + x2 = 3 + 2x Solving 88 + x2 = 3 + 2x Solving for variable 'x'. Reorder the terms: 88 + -3 + -2x + x2 = 3 + 2x + -3 + -2x Combine like terms: 88 + -3 = 85 85 + -2x + x2 = 3 + 2x + -3 + -2x Reorder the terms: 85 + -2x + x2 = 3 + -3 + 2x + -2x Combine like terms: 3 + -3 = 0 85 + -2x + x2 = 0 + 2x + -2x 85 + -2x + x2 = 2x + -2x Combine like terms: 2x + -2x = 0 85 + -2x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-85' to each side of the equation. 85 + -2x + -85 + x2 = 0 + -85 Reorder the terms: 85 + -85 + -2x + x2 = 0 + -85 Combine like terms: 85 + -85 = 0 0 + -2x + x2 = 0 + -85 -2x + x2 = 0 + -85 Combine like terms: 0 + -85 = -85 -2x + x2 = -85 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 = -85 + 1 Reorder the terms: 1 + -2x + x2 = -85 + 1 Combine like terms: -85 + 1 = -84 1 + -2x + x2 = -84 Factor a perfect square on the left side: (x + -1)(x + -1) = -84 Can't calculate square root of the right side. The solution to this equation could not be determined.
