How do you multiply: #(a-5)(a^2+5a+25)#?
- We know the identity
#color(blue)(x^3 - y^3 = (x-y)(x^2+xy+y^2)#
The expression given to us is in the form
Hence the expression can directly be written as
- But if we are not familiar with the identity we can use the Distributive Property of Multiplication to solve this expression
