Binomial Theorem G11

Can you evaluate the square of 98? Yes, we can do it easily by writing it as subtraction of 100 and 2, and apply the formula for the whole square of a + b. Now, what if you need to find the value of 98 to the power 5. Can you solve this easily? No right? Well, here comes the Binomial Theorem to our rescue. In this chapter, we will be learning the general formula for the binomial theorem that will help you solve questions like the ones above. Moreover, we will learn about Pascal’s triangle and combinations in the binomial theorem.
