( ) 8x²+18xy+9y²

( )16x²+24x+9

( )12²+12x+9x²

( )8x³-12x+9​

Answer 1

Resposta:

( ) 8x²+18xy+9y²

(X)16x²+24x+9

( )12²+12x+9x²

( )8x³-12x+9​

Explicação passo-a-passo:

Fórmula

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

(4x+3)^2 = (4x)^2 + 2*4x*3+(3)^2

4x*4x= 16x^2

3*3= 9

16x^2 + 24x + 9

( X)16x²+24x+9
