Show transcript
There are other methods to find the solutions of a quadratic equation.
One of these methods is called completing the square.
Completing the square is useful when the quadratic cannot be easily factorised.
Quadratic equations of the form $$ax^2 + bx + c = 0$$ (where $$a$$ ≠ 1) can be solved by completing the square.
