Question

Cubos de Binomioss.

(6-7a²)³​

Answer 1

Cubo de un binomio:

(a+b)^3 = a^3 +3a^2(b) + 3a(b^2) + b^3

(a-b)^3 = a^3 - 3a^2(b) + 3a(b^2) - b^3

${(6 - 7 {a}^{2} )}^{3}$

${6}^{3} - 3( {6}^{2} )( 7 {a}^{2}) + 3(6)( { {7a}^{2} })^{2} - ( { { 7a}^{2}) }^{3}$

$216 - 756 {a}^{2} + 882 {a}^{4} - 343 {a}^{6}$

Espero te sirva de ayuda.
