Question

find the following product
(x-3/x)(x-3/x)​

Answer 1

Answer:

(x-3/x)(x-3/x)

=(x-3/x)²

(a-b)²=a²+b²-2ab

=x²+(3/x)²-2x×3/x

=x²+9/x²-6

=x⁴-x²+9

Answer 2

ANSWER:

x2-9

EXPLANATION:

Given (x+3)(x−3)

By using the formula (a+b)(a−b)=a

2

−b

2

Applying the formula we get

(x+3)(x−3)=x

2

−3

2

∴(x+3)(x−3)=x 2 −9
