Question

5x³-3x²+4x+2 find its zeros
​

Answer 1

Answer:

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
