p=3 !

-2p-18
Without prior knowledge of the value of q or r, it is impossible to calculate the answer to this equation.
p2 + 2pq + q2 = 1q2 + 2pq + (p2 - 1) = 0q = 1/2 [ -2p plus or minus sqrt( 4p2 - 4p2 + 4 ) ]q = -1 - pq = 1 - p
If: 2p+5r = q Then: p = (q-5r)/2
It is an expression that can be simplified to: 3p+q
5p-7q
3q + 2p
p=3 !
It is 2p + 3q. This is an expression and so cannot be solved. It cannot be simplified, and without information about the values of p and q, it cannot be evaluated.
No, it is a binomial. A monomial only has one term. A plus or minus sign creates or separates terms.
