Question

2. Write the coefficients of x^2? in each of the
following:
(i) 2+x^2+x
(ii) 2-x^2+x^3
(iii)(π/2)×x^2+x
(iv)√2x-1​

Answer 1

Answer:

1.,1,1,2

Step-by-step explanation:

2+x^2+x=1

similarly to the equation one

Answer 2

Answer:

Coefficient of x 2 in ax 2 + bx + c = 0 is a.

Hence, coefficients of x 2 in

(i) 2 + x 2 + x is 1

(ii) 2 − x 2 + x 3 is − 1

(iii) π 2x 2 + x is π 2

(iv) √2x − 1 is 0
