Answer 2

Given:

2+x²+x

2-x² + x³

πx² / 2 + x

√2 x-1

To Find:

The Coefficient of x²

Solution:

We know,

The constant before x² is the coefficient of x²

1) 2+x²+x : here 1 is the coefficient of x²

2) 2-x² + x³ : here -1 is the coefficient of x².

3) πx² / 2 + x : here 0 is the coefficient of ² as there is no x² term present.

4) √2 x-1 : here 0 is the coefficient of x² as there is no x² term present.

So, The Coefficient of x² are 1 , -1 , 0 , 0.
