(5x2-1)2
(5x2-1)2
(9x2-1)2

Answer 1

Resposta:

(5-x)2

$25 - 10x + {x}^{2}$

(X-y)2

${x}^{2} - 2xy + {y}^{2}$

(2x-5)2

$4 {x}^{2} - 20x + 25$

(3x-2y)2

$9 {x}^{2} - 12xy + 4 {y}^{2}$

(5x2-1)2

$25 {x}^{4} - 10 {x}^{2} + 1$

(5x2-1)2

$25 {x}^{4} - 10 {x}^{2} + 1$

(9x2-1)2

$81 {x}^{4} - 18 {x}^{2} + 1$
