Question

expand the identity
(a)(x+y)^3
(b)(p-q)^3
(c)(x+a)(x+b)
(d)(a+b)(a-b)
(e)(a+b+c)^3
(f)x^3+y^3
(g)x^3-y^3
(h)(x+y+z)(x^2+y^2+z^2-xy-yz-zx)​

Answer 1

Answer:

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

Answer 2

Step-by-step explanation:

a)x³+y³+3x²y+3xy²

b)p³-q³-3p²q+3pq²

c)x2+bx++ax+ab

d)a²-b²

e) a³+b³+c³+3(a+b)(b+c)(c+a)

f)(x+y)(x²-xy+y²)

g)(x-y)(x²+xy+y²)

h)x³+y³+z³-3xyz

Here is ur solution...

Hope so it will help you dear ☺️☺️
