Question

p^2qr+pq^2r+pqr^2+-3pq^2r-2pqr^2​

Answer 1

Given:

${p}^{2} qr + p {q}^{2} r + pq {r}^{2} - 3p {q}^{2} r - 2pq {r}^{2}$

To Find:

The sum of the given equation.

Solution:

we have,

${p}^{2}qr + pq^{2} r + pqr^{2} - 3pq^{2} r - 2pqr ^{2}$

Putting like terms together. (Like terms are the terms having same algebraic expressions.)

${p}^{2} qr + p {q}^{2} r - 3p {q}^{2} r + pq {r}^{2} - 2pq {r}^{2}$

solving the above expression,

${p}^{2} qr - 2p {q}^{2} r - pq {r}^{2}$

The above expression cannot be solved further as the algebraic expressions are not like terms.

Hence, the sum of the given equation is,

${p}^{2} qr - 2p {q}^{2}r - pq {r}^{2}$
