Question

Simplify ( 5 − 3)( 5 + 3)​

Answer 1

16

Step-by-step explanation:

first we multiply both the bracket with each other that is

(5-3)(5+3)

5(5+3) -3(5+3)

that will be:

25+15-15-9

15-15=0

so, 25-9=16.

Hope it answers your question ;)

Answer 2

Answer:

The correct answer is 16

Step-by-step explanation:

For this,

We will use one identity

(a-b)(a+b)=a(a+b)-b(a+b)

=a^2+ab-ab-b^2

=a^2-b^2

Or just,

(a-b)(a+b)=a^2-b^2

So,( 5 − 3)( 5 + 3)=5^2-3^2

=25-9

=16
