Question

factorise p -q^3+ q- r^3 + r- p^3

Answer 1

Answer:

$(p+q+r)(1-p^{2})(1-q^{2})(1-r^{2})$

Step-by-step explanation:

$p-q^{3} +q-r^{3} +r-p^{3}\\p-p^{3} +q-q^{3}+r-r^{3}\\\\p(1-p^{2})+q(1-q^{2})+r(1-r^{2})\\(p+q+r)(1-p^{2})(1-q^{2})(1-r^{2})$

Answer 2

Step-by-step explanation:

p - q³ + q - r³ + r - p³

= -p² - q² - r²
