Question

Please only 7th and 8th please please

Answer 1

Step-by-step explanation:

highest power of polynomial is the degree of that polynomial

Answer 2

Answer:

7th. p(x)= x^2 -2x

answer is (0,2)

because if we let p(0)= x^0 -2×0

=0-0 =0

if we let p(2) = 2^2 - 2×2

= 4-4=0

8th. (7x^4 +6x^3 -root2 x^2 -x -4)+(-4-x-root2 x^2 +6x^3 +7x^4)

first of all we do simplify this

(7x^4 +6x^3 -root2 x^2 -x -4)+(-4-x-root2 x^2 +6x^3 +7x^4)

7x^4 +6x^3 -root2 x^2 -x -4 -4-x-root2 x^2 +6x^3 +7x^4

14x^4 + 12x^3 -2 root2 x^2 -2x -8

and the correct answer is 4

because Degree of polynomial is known as highest power of any equation.

in this equation 14x^4 have highest power which is 4 therefore the correct answer is 4.

I hope it is useful for you.

please make me brainliest.
