Question

The lcm of x3-a3 and (x-a) 2 is

Answer 1

Answer:

Step-by-step explanation:

L C M of (x³-a³) and 2(x-a) = ( x-a) ×(x²-a²) ×2

                                            = 2(x³+a³-a²x-ax²)

so,

    LCM oF x³-a³  and 2(x-a) is 2(x³+a³-a²x-ax²)

Answer 2

Use formula of $(x^{3}-a^{3}) = (x-a)(x^{2}+xa+a^{2})$

Step-by-step explanation:

$(x^{3}-a^{3}) = (x-a)(x^{2}+xa+a^{2})$

$(x-a)^{2} = (x-a)(x-a)$

LCM of $(x^{3}-a^{3})$ and$(x-a)^{2}$ = $(x-a)^{2}$$(x^{2}+xa+a^{2})$
