Question

The square of (2x+y) is​

Answer 1

Step-by-step explanation:

In this question, we need to expand the term (2x +y )^2

As we all know that (a + b)^2 = a^2 + b^2 + 2ab

We can expand the given term in the same way,

==> ( 2x + y)^2

==> (2x + y)^2 = 4x^2 + y^2 + 8xy

FORMULA TO REMEMBER

• ( a + b)^2 = a^2 + b^2 + 2ab
