# Write the coefficients of x^{2} in each of the following:

(i)

(ii)

(iii)

(iv)

Answer :

Coefficient of a variable in an equation is the number that is multiplied with that variable. Therefore for finding out the coefficient of x^{2} in the equations given below. Watch for the numbers multiplied with x^{2} and include the positive or negative sign.

Since coefficient is the multiplicative part to a variable in a single term, then **(i)** Coefficients of x^{2} = 1**(ii)** Coefficients of x^{2} = -1

**(iii)** Coefficients of x^{2} =

**(iv)** Coefficients of x^{2} = 0
