Simplifying (x + 1)(x + 9) = 9x Reorder the terms: (1 + x)(x + 9) = 9x Reorder the terms: (1 + x)(9 + x) = 9x Multiply (1 + x) * (9 + x) (1(9 + x) + x(9 + x)) = 9x ((9 * 1 + x * 1) + x(9 + x)) = 9x ((9 + 1x) + x(9 + x)) = 9x (9 + 1x + (9 * x + x * x)) = 9x (9 + 1x + (9x + x2)) = 9x Combine like terms: 1x + 9x = 10x (9 + 10x + x2) = 9x Solving 9 + 10x + x2 = 9x Solving for variable 'x'. Reorder the terms: 9 + 10x + -9x + x2 = 9x + -9x Combine like terms: 10x + -9x = 1x 9 + 1x + x2 = 9x + -9x Combine like terms: 9x + -9x = 0 9 + 1x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-9' to each side of the equation. 9 + 1x + -9 + x2 = 0 + -9 Reorder the terms: 9 + -9 + 1x + x2 = 0 + -9 Combine like terms: 9 + -9 = 0 0 + 1x + x2 = 0 + -9 1x + x2 = 0 + -9 Combine like terms: 0 + -9 = -9 1x + x2 = -9 The x term is 1x. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. x + 0.25 + x2 = -9 + 0.25 Reorder the terms: 0.25 + x + x2 = -9 + 0.25 Combine like terms: -9 + 0.25 = -8.75 0.25 + x + x2 = -8.75 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = -8.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
