(x + 1) and (x + 2) are monomial factors of the polynomial x2 + 3x + 2 (x + 1) and (x + 3) are monomial factors of the polynomial x2 + 4x + 3 (x + 1) is a common monomial factor of the polynomials x2 + 3x + 2 and x2 + 4x + 3
If x = 8 and y = 10 then it is 44.

If x = 8 and y = 10 then it is 44.
The expression "8x plus 5x" simplifies to ( (8 + 5)x ), which is ( 13x ). The reference to "when x8" seems unclear, but if you meant "when x = 8," then substituting gives ( 13(8) = 104 ). Thus, the expression evaluates to 104 when ( x = 8 ).
X -8 same as, 1/X8 ====
No. It simplifies to a monomial.
-1 x 7 x c x c = -7c2
No. It's a binomial, (whose value happens to be zero no matter what 'x' is).
