Question

(x + 3y/2) . (x - 3y/2)

Answer 1

Resposta:

$( x + \frac{3y}{2} ) \times (x - \frac{3y}{2} ) \\ \\ {x}^{2} - ( \frac{3y}{2} ) ^{2} \\ \ \\ \ {x}^{2} - \frac{ {9y}^{2} }{4}$

A resposta e isso ;)

Answer 2

Resposta:

x^2 - 9y^2/ 4

Explicação passo a passo:

= (x + 3y/2) . (x - 3y/2)

= x^2 - (3y/2)^2

= x^2 - 9y^2/ 4
