please say the answers ita really urgent please​

Answer 1

Answer:

Step-by-step explanation:

Ans 1 (a) - (x^3/x^2)-(x^4/x^2)+(x^8/x^2)

After cancelling the powers we get = x-x^2+x^4 . So, the degree is 4.

(b) x(x-3)+3(x-3)= x^2-3x+3x-9= x^2-9

Here degree is 2.

Ans 2. p(0)= (0+2)(0-2)= 2*-2= -4

p(1) = (1+2)(1-2)= 3*-1= -3

p(-2) = (-2+2)(-2-2) = 0* -4= 0

Ans 3. f(2)= (2)^2- 5* 2 + 1 = 4-10+1 = -5

f(-1) = (-1)^2 -5* -1 +1 = 1+5+1 = 7

f(1/3) = (1/3)^2 -5/3+1 = 1/9-5/3+1 = (1-10+9)/9 = 0/9 = 0

f(2)-f(-1)+f(1/3) = -5-7+0= -12

Hope it helps you. Dear Mark me the brainliest plz.
