Question

Calcule os produtos notáveis ​

Answer 1

a) (x+1)² = (x+1)*(x+1) = x²+1x+1x+1= x²+2x+1

b) (2x+2)² = (2x+2)*(2x+2) = 4x²+4x+4x+4 = 4x²+8x+4

c) (c-3)² = (c-3)*(c-3) = c²-3c-3c+9 = c²-6c+9

d)

e) (2-c)² = (2-c)*(2-c)= 4-2c-2c+c² = c²-4c+4

f) (6+c³)² = (6+c³)*(6+c³) = 36+6c³+6c³+ c6 (c elevado a 6)= 36+12c³+ c6
