Factorize each of the following expressions:a3+b3+a+b

Given,a3+b3+a+b = (a3 + b3) + (a+b)= (a+b) (a2 – ab +b2) +a+b= (a+b)(a2 – ab +b2+1)

Q20 of 111 Page 5

Factorize each of the following expressions:
a³+b³+a+b

Given,

a³+b³+a+b = (a³ + b³) + (a+b)

= (a+b) (a² – ab +b²) +a+b

= (a+b)(a² – ab +b²+1)
