Lutasin ang 28p^{7}q^{5}-35p^5q^7-7p^4q^4

$$28 p ^ { 7 } q ^ { 5 } - 35 p ^ { 5 } q ^ { 7 } - 7 p ^ { 4 } q ^ { 4 }$$

I-factor

$$7p^{4}q^{4}\left(-5pq^{3}+4qp^{3}-1\right)$$

Mga Hakbang ng Solution

I-factor out ang 7.

$$7\left(4p^{7}q^{5}-5p^{5}q^{7}-p^{4}q^{4}\right)$$

Isaalang-alang ang 4p^{7}q^{5}-5p^{5}q^{7}-p^{4}q^{4}. I-factor out ang p^{4}q^{4}.

$$p^{4}q^{4}\left(4p^{3}q-5pq^{3}-1\right)$$

I-rewrite ang kumpletong naka-factor na expression.

$$7p^{4}q^{4}\left(4p^{3}q-5pq^{3}-1\right)$$

I-evaluate

$$7\left(-5pq^{3}+4qp^{3}-1\right)\left(pq\right)^{4}$$
