Verified answer

--(9p^4q^3 - 6p^2q^4 + 5p^3q^2)/3p^2q^2

= 3p^2q - 2pq^2 + 5p/3

Use the FOIL technique to multiply 2 binomials: First words: 5a*6a=30a^2 Outer words:5a * (-5)= -25a inner words: -2 * 6a = -12a very last words:-2 * -5= +10 now upload them jointly 30a^2-25a-12a+10 upload like words 30a^2-37a+10 finished! you presently have what's prevalent because the quadratic trinomial
