Topic - Algebraic Expression 1.Check if the following algebraic expression are polynomial or not.If so,write their degree. (2) i) 4x 3 -3x 2+11x-7 ii) 9x 2 -9/x 2​

Answer 1

Step-by-step explanation:

ANSWER:

(i)

    2a +   b + 7

    4a + 2b + 3   

    ---------------------

    6a + 3b + 10

(ii)

      3x +   y - 8

  - 7x +   y +  4  

    ---------------------

   -4x + 2y - 4

(iii)

    3x2 + 5x - 4

 -2x2 + 8x + 11

   ---------------------

      x2 + 13x + 7

(iv)

       5√x - 4√y + 2    2√x + 7√y - 5   7√x +3√y  - 3

Answer 2

$1) \: \: 4 {x}^{3} - 3 {x}^{2} + 11x - 7$

$yes \: \: it \: \: is \: \: polynomial \: 3 {x}^{2}$

$2) \: \frac{9 {x }^{2} - 9}{ {x}^{2} }$

$yes \: \: it \: \: is \: \: polynomial \: 9 {x}^{2}$
