b) (2+g)²=
c) (5+z)²=
d) (o+10)²=
e) (2/3×+3/2y)=
f) (×+9)²=
g) (d+7)²=
h) (d+e)²=​

Answer 1

Resposta:

a) (a + c)² = a² + 2ac + c²

b) (2 + g)² = 4 + 4g + g²

c) (5 + z)² = 25 + 10z + z²

d) (o + 10)² = o² + 20o + 100

e) (2/3x + 3/2y)² = 4/9x² + xy + 9/4y²

f) (x + 9)² = x² + 18x + 81

g) (d + 7)² = d² + 14d + 49

h) (d + e)² = d² + 2de + e²
