Two polynomials are added and the sum is 3x^2-y+4. For each statement, state weather it is always true, sometimes true or never true. Explain or provide a counter example to justify our answer.
a) both are monomials

b) both include a y-term

c) if there is a x-term in one polynomial, then there must be a x-term in the other

d) both are monomials

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.

step-by-step explanation:

2nd one in the first row is correct

differentiate (x^14(x^-2)^4with respect to the variable

the parentheses don't balance in your input.

differentiate 0 with respect to

the final answer is

0

hope this

you need to know that the corresponding sides and angles are the same.
