Question

desenvolva o quadrado da soma de dois termos

a) (a+7)2=

b) (3x+1)2=

c) (5+2m)2=

d) (a+3x)2=

e) (5x2 + 1)2=

Answer 1

a) = (a+7) (a+7)
= a²+2a7+7²
= a²+14a+49

b) = (3x+1) (3x+1)
= 9x² +6x+1

c) = (5+2m) (5+2m)
= 4m² + 20m +25

d) = (a+3x) (a+3x)
= a² +6xa+9x²

e) =(5x²+1) (5x²+1)
= 25x⁴ + 10x + 1
