Question

1) (y+6)²

2) (m-n)²


3) (10+2) . (10-2)

Me ajudem pfv

Answer 1

1)y^2+12y+36
2)m^2-2mn+n^2
3)100-4

Answer 2

Olá!!!

Resolução!!!

1)
= ( y + 6 )²
= ( y )² + 2 • y • 6 + 6²
= y² + 12y + 36

2)
= ( m - n )²
= ( m )² - 2 • m • n + ( n )²
= m² - 2mn + n²

3)
= ( 10x + 2 ) • ( 10x - 2 )
= ( 10x )² - 2²
= 100x - 4

Espero ter ajudado!!!
