Write the coefficients of x² in each of the following 1) 2+x²+x 2) 2-x²+x³

1) 1 and 2) - 1

Step-by-step explanation:

1) 2+x²+x

+x² ⇒ coefficient of x² is 1

2) 2-x²+x³

-x² ⇒ coefficient of x² is - 1

(1) 1 (2) 0

Step-by-step explanation:

Looking at 1) 2+x²+x;

The coefficient of x is 1 because we see + x in the express which is the same as 1 * x = x.

2) Looking at 2) 2-x²+x³

There is no expression with x but we have x^2, x^3. Hence the coefficient of x is 0 because 0*x = 0
