Question

(x-5) (x-5) ,Use suitable identities to find the given product.

Answer 1

(a-b)×(a-b)=(a-b)^2
.
so it will be

(x-5)^2

=x^2+25-10x

=x^2-10x+25

hope it will help u

Answer 2

Solution :

******************************************

We know the algebraic identity :

( a - b )² = a² - 2ab + b²

******************************************

Now ,

( x - 5 )( x - 5 )

= ( x - 5 )²

= x² - 2 × x × 5 + 5²

= x² - 10x + 25

Therefore ,

( x - 5 )² = x² - 10x + 25
