Claro, vamos resolver essa questão passo a passo.

Primeiro, vamos calcular [tex]\(x^2\)[/tex] onde [tex]\(x = -3\)[/tex].

[tex]\[ x^2 = (-3)^2 = 9 \][/tex]

Agora, vamos calcular [tex]\(y^2\)[/tex] onde [tex]\(y = 2\)[/tex].

[tex]\[ y^2 = 2^2 = 4 \][/tex]

Com esses valores determinados, agora podemos proceder para calcular a expressão [tex]\( x^2 - y^2 \)[/tex]:

[tex]\[ x^2 - y^2 = 9 - 4 = 5 \][/tex]

Então, o valor numérico da expressão [tex]\( x^2 - y^2 \)[/tex] para [tex]\( x = -3 \)[/tex] e [tex]\( y = 2 \)[/tex] é [tex]\( 5 \)[/tex].
