Question

Expand the polynomials and simplify.


(0.2x–0.5y)^2

Answer 1

Answer: The simplify and expanded form of the polynomial is :

`0.04x^2+0.25y^2-0.2xy`

Explanation:

Since we have given that

`(0.2x-0.5y)^2`

As we know the formula

So, we will apply this,

Here,

a = 0.2x

b = 0.5y

So, it becomes,

`(0.2x-0.5y)^2\\\\=(0.2x)^2+(0.5y)^2-2* 0.2x* 0.5y\\\\=0.04x^2+0.25y^2-0.2xy`

Hence, the simplify and expanded form of the polynomial is :

`0.04x^2+0.25y^2-0.2xy`
