Simplifying (a + -1x)(b + -1x) = x2 Multiply (a + -1x) * (b + -1x) (a(b + -1x) + -1x * (b + -1x)) = x2 ((b * a + -1x * a) + -1x * (b + -1x)) = x2 ((ab + -1ax) + -1x * (b + -1x)) = x2 (ab + -1ax + (b * -1x + -1x * -1x)) = x2 (ab + -1ax + (-1bx + 1x2)) = x2 (ab + -1ax + -1bx + 1x2) = x2 Solving ab + -1ax + -1bx + 1x2 = x2 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add 'bx' to each side of the equation. ab + -1ax + -1bx + bx + 1x2 = bx + x2 Combine like terms: -1bx + bx = 0 ab + -1ax + 0 + 1x2 = bx + x2 ab + -1ax + 1x2 = bx + x2 Add '-1x2' to each side of the equation. ab + -1ax + 1x2 + -1x2 = bx + x2 + -1x2 Combine like terms: 1x2 + -1x2 = 0 ab + -1ax + 0 = bx + x2 + -1x2 ab + -1ax = bx + x2 + -1x2 Combine like terms: x2 + -1x2 = 0 ab + -1ax = bx + 0 ab + -1ax = bx Combine like terms: bx + -1bx = 0 ab + -1ax + -1bx = 0 The solution to this equation could not be determined.
