Question

producto notable
-binomios al cuadrado-

(5x³-4a³)²​

Answer 1

Respuesta:

$25 {x}^{6} - 40 {a}^{3} {x}^{3} + 16 {a}^{6}$

Explicación paso a paso:

$(5 {x}^{3} - 4 {a}^{3})^{2}$

$(5 {x}^{3})^{2} - 2 \times 5 {x}^{3} \times 4 {a}^{3} + (4 {a}^{3})^{2}$

$(25 {x}^{6} - 2 \times 5 {x}^{3} \times 4 {a}^{3} + (4 {a}^{3})^{2}$

$25 {x}^{6} - 40 {a}^{3} {x}^{3} + (4 {a}^{3})^{2}$

$r = 25 {x}^{6} - 40 {a}^{3}{x}^{3} + 16 {a}^{3}$
