Question

7. Find the following products :
(i) 6x2 x (3x + 3) × (4x - 1)​

Answer 1

Step-by-step explanation:

4x2 – 3x + 7

⇒ 4x2 – 3x + 7x°

∵ All the exponents of x are whole numbers.

∴ 4x2 – 3x + 7 is a polynomial in one variable.

(ii)

∵ All the exponents of y are whole numbers.

∴ is a polynomial in one variable.

(v) x10 + y3 + t50

∵; Exponent of every variable is a whole number,

1. ∴ x10 + y3 + t50 is a polynomial in x, y and t, i.e. in three variables.
