Question

Express in polynomial-5(2+b) -6b(2+b)​

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,

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