Learning Multiplication in Algebra

 Multiplication in Algebra

Lets apply the grid method learnt earlier in this scenario as well

what have we done here we have to solve (A² + B²) x(A² + B²)

To help understand the multiplication in algebra we  make a grid (4x4 in this case)  and then in each box we do the multiplication of each element and we get  answer in each box.

Now we take all the answers and then add these up.so we have the following

A⁴  +A² B² +A² B² +B⁴

 we have two same expressions. A² B² +A² B²  and this can be written as     2 A² B²

So we have the answer as  A⁴  + 2A² B² +B⁴ 

^{This can be used to solve any multiplication algebraic expression. more the number of terms are more columns you need to create. This is the easiest way to learn multiplication when you start learning Algebra.}
