Simplifying ax2 + bx2 + c = 0 Solving ax2 + bx2 + c = 0 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-1bx2' to each side of the equation. ax2 + bx2 + -1bx2 + c = 0 + -1bx2 Combine like terms: bx2 + -1bx2 = 0 ax2 + 0 + c = 0 + -1bx2 ax2 + c = 0 + -1bx2 Remove the zero: ax2 + c = -1bx2 Add '-1c' to each side of the equation. ax2 + c + -1c = -1bx2 + -1c Combine like terms: c + -1c = 0 ax2 + 0 = -1bx2 + -1c ax2 = -1bx2 + -1c Divide each side by 'x2'. a = -1b + -1cx-2 Simplifying a = -1b + -1cx-2
