Yes.

It is an algebraic expression.

the answers is d

That factors to y(y2 + 7y - 5)

The coefficient of X is 1

X2+Y3+15 All you can do is simplify it.

Yes.

It is an algebraic expression.

y + y4 = y5 , possibly. Except that conventionally, the number (or coefficient) would be written first. y + y4 = y*(1 + y3) = y(1 + y)*(1 - y + y2)

No.

(x2 - xy + y2)(x + y)

the answers is d

That factors to y(y2 + 7y - 5)

The coefficient of X is 1

x^2 - xy + y^2

y3 + 9y + 10y - 5/y + 2 can not be solved, as it is not an equation. If you would like to simplify it, you can reduce it a bit: = y3+ 19y - 5/y + 2

There is no single coefficient for that equation, as a coefficient is the number by which any term is multiplied. The coefficients in that equation are 5, 2, 4 and 3.
