Question

Find p(0),p(1),p(-1)
a) p(x) = 3x+S
b) p(x) = 3x2+6x+1
c) p(x) = 2x2-3x+4​

Answer 1

Answer:

Which of the following expressions are polynomials in one variable and which are not? State reasons for your answer.

Ans. (i) 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.
