Question

simplify : a²(b²-c²)+b²(c²-a²)+c²(a²+b²)​

Answer 1

Step-by-step explanation:

a^2b^2-a^2c^2+a^2b^2-b^2c^2+a^2c^2-b^2c^2

=(ab)^2-(ac)^2+(ab)^2-(bc)^2+(ac)^2-(bc)^2

=2(ab)^2-2(bc)^2

Answer 2

Answer:

$2( {bc}) ^{2}$

Step-by-step explanation:

${a}^{2} {b}^{2} - {a}^{2} {c}^{2} + {b}^{2} {c}^{2} - {b}^{2} {a}^{2} + {c}^{2} {a}^{2} + {c}^{2} {b}^{2}$

$2 {b}^{2} {c}^{2}$

$2( {bc}) ^{2}$
