Question

verify x3+y3=(x+y) (x2-xy+y2)​

Answer 1

Step-by-step explanation:

let x=2; y=3

x^3+y^3=2^3+3^3

=8+27

=35------------(1)

(x+y)(x^2-xy+y^2)=(2+3)(2^2-2*3+3^2)

=(5)(4-6+9)

=(5)(13-6)

=5*7

=35------------(2)

from (1)& (2)

x^3+y^3=(x+y)(x^2-xy+y^2)

hence verified

Answer 2

Answer:

Step-by-step explanation:

Step-by-step explanation:

(x³-y³) =(x-y) (x²+xy+y²)

R.H.S. =(x-y)(x²+xy+y²)

=x³+x²y+xy²-x²y-xy²-y³

=x³-y³

L.H.S=R.H.S

x³-y³=(x-y)(x²+xy+y²) PROVED...
