Question

write the coefficient of x³ in each of the following.
( 1). x³+x+1.
(2). 2-x³+x².
(3). √2x³+5.
(4). 2x³+5.
​

Answer 1

A coefficient is a multiplicative factor in some term of a polynomial. It is the constant written before the variable.

Therefore,

(i) The constant written before x3 in x3 + x + 1 is 1.

∴ The coefficient of x3 in x3 + x + 1 is 1.

(ii) The constant written before x3 in 2 – x3 + x2 is -1.

∴ The coefficient of x3 in 2 – x3 + x2 is -1.

(iii) The constant written before x3 in √2x3 + 5 is √2.

∴ The coefficient of x3 in √2x3 + 5 is √2.

(iv) The constant written before x3 in 2x3 + 5 is 2.

∴ The coefficient of x3 in 2x3 + 5 is 2.
