Question

Subtract 3p cube - 5p square q + 2q square from q square + p square q - 4p cube

Answer 1

Step-by-step explanation:

$\: \: \: \: \: {q}^{2} + {p}^{2} q - 4 {p}^{3} \\ \underline{ - (2 {q}^{2} + 3 {p}^{3} - 5 {p}^{2}q)}$

$\: \: \: \: {q}^{2} + {p}^{2} q - 4 {p}^{3} \\ \underline{ - 2 {q}^{2} + 5 {p}^{2}q - 3 {p}^{3} }$

$- {q}^{2} + 6 {p}^{2} q - 7 {p}^{3}$

$6 {p}^{2} q - {q}^{2} - 7 {p}^{3}$
