Simplifying 9x2 + -3(a + b) * x + ab = 0 Reorder the terms for easier multiplication: 9x2 + -3x(a + b) + ab = 0 9x2 + (a * -3x + b * -3x) + ab = 0 9x2 + (-3ax + -3bx) + ab = 0 Reorder the terms: ab + -3ax + -3bx + 9x2 = 0 Solving ab + -3ax + -3bx + 9x2 = 0 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '3bx' to each side of the equation. ab + -3ax + -3bx + 3bx + 9x2 = 0 + 3bx Combine like terms: -3bx + 3bx = 0 ab + -3ax + 0 + 9x2 = 0 + 3bx ab + -3ax + 9x2 = 0 + 3bx Remove the zero: ab + -3ax + 9x2 = 3bx Add '-9x2' to each side of the equation. ab + -3ax + 9x2 + -9x2 = 3bx + -9x2 Combine like terms: 9x2 + -9x2 = 0 ab + -3ax + 0 = 3bx + -9x2 ab + -3ax = 3bx + -9x2 Reorder the terms: ab + -3ax + -3bx + 9x2 = 3bx + -3bx + -9x2 + 9x2 Combine like terms: 3bx + -3bx = 0 ab + -3ax + -3bx + 9x2 = 0 + -9x2 + 9x2 ab + -3ax + -3bx + 9x2 = -9x2 + 9x2 Combine like terms: -9x2 + 9x2 = 0 ab + -3ax + -3bx + 9x2 = 0 The solution to this equation could not be determined.
