Example: Factorize, 27x3-8. Solution: Given that, 27x3-8. We can write this as, = (3x)3-(2)3 This is in the form of a3-b3 = (a-b)(a2+ab+b2) here, a = 3x and b = 2, substitute these value in the above equation, we get = (3x-2)(9x2+6x+4) Directions: Solve the following problems. Also write at least ten examples of your own. |
