Solve : 3x2-...

Question

Solve :
$(3 x^{2} - 2 a x + 3 a^{2})^{3}$

Open in App

Solution

${(3 x^{2} - 2 a x + 3 a^{2})}^{3}$

$= (3 x^{2} - 2 a x + 3 a^{2}) (3 x^{2} - 2 a x + 3 a^{2}) (3 x^{2} - 2 a x + 3 a^{2})$

$= (9 x^{4} - 12 a x^{3} + 22 a^{2} x^{2} - 12 a^{3} x + 9 a^{4}) (3 x^{2} - 2 a x + 3 a^{2})$

$= 27 x^{6} - 54 a x^{5} + 117 a^{2} x^{4} - 116 a^{3} x^{3} + 117 a^{4} x^{2} - 54 a^{5} x + 27 a^{6}$
