Question

Find the product:-

(x^2-a^2)*(x-a)​

Answer 1

Step-by-step explanation:

Suppose (a−b) and (c−d) are two binomials. By using the distributive law of multiplication over addition twice, we may find their product as given below.

(a−b)×(c−d)=a×(c−d)−b×(c−d)=(a×c−a×d)−(b×c−b×d)

=ac−ad−bc+bd

Let , a=x²

,b=a² ,c=x,d=a

Now, =x²

×(x−a)−a²×(x−a)

=[(x 2 ×x)+((a 2 ×x)+(a 2 ×−a)]

=[x 3 −x 2 a−a 2 x+a 3 ]
