## A little note : IITJEE foundation maths

**Example:**

Solve

**Solution:**

We have

that is, call this as Equation (1)

Transposing,

Hence, , or

Thus, the roots are 0 and

**Note:**

In equation (1), above, we might have divided both sides by x and obtained the simple equation , hence, , which is one of the solutions of the given equation. But, the student must be particularly careful to notice that whenever an x, or a factor containing x, is removed by division from every term of an equation, it must not be neglected, since the equation is satisfied by , which is therefore, one of the roots.
