Question

use a suitable identity to get each of the following products
(x-3) (x-3)​

Answer 1

Answer:

(x-3) , (x-3)

(x-3)=0 , (x-3)=0

x=3 , x=3

Answer 2

Answer:

(x-3)(x-3) = (x-3)^2

Identity:-

$\tt( {x - y})^{2} = {x}^{2} + {y}^{2} - 2xy$

Now using the above identity to solve the above question

$\tt \implies ({x - 3})^{2} = {x}^{2} + {3}^{2} + 2 \times x \times 3 \\ \tt \implies {x}^{2} + 9 - 6 x$
