Example: Expand (Ö3 + Ö2)(Ö3 - Ö2). Solution: The above problem in the form of (a + b)(a - b) = a2 - b2. Here a = Ö3 and b =Ö2. Substitute these values in the above formula we get, (Ö3 + Ö2)(Ö3 - Ö2) = (Ö3)2 - (Ö2)2. = 3 - 2 = 1 Directions: Solve the following problems. Also write at least ten examples of your own. |
