Question

How many terms will the following expression have once it is simplified?

Answer 1

B. 2

Explanation:

we are given

`3x(x+1)+x`

Firstly, we will distribute 3x

`a(b+c)=a* b+a* c`

we can use this formula

and we get

`3x(x+1)+x=3x* x+3x* 1+x`

`3x(x+1)+x=3x^2+3x+x`

now, we can combine like terms

`3x(x+1)+x=3x^2+4x`

we can see that there are two terms after simplifying

so, there are two terms

option-B

Answer 2

B

Explanation:

Let's multiply this out and combine like terms:

`3x(x+1)+x\\=3x^2+3x+x\\=3x^2+4x`

So there are 2 terms.

Answer choice B is right.
