Determine if the expression -x^4 - 2x^2 is a polynomial or not. If it is a polynomial, state the type and degree of the polynomial

3/6   and 9/18

step-by-step explanation:

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

step-by-step explanation:

answer: the anser is 3
