Answer 1

Question :-

Use suitable identity to get the products

a) (x +5 ) (x – 5)

Using identity :-

$\boxed{\mathsf{(x\:+\:y)\:(x\:-\:y)\:=\:x^2\:-\:y^2}}$

Solution :-

$\mathsf{:\longrightarrow\:(x\: +\:5 )\:(x \:-\:5)}$

$\mathsf{:\longrightarrow\:(x)^{2}\:-\:(5)^{2}}$

$\mathsf{:\longrightarrow\:x^{2}\:-\:25}$

Final Answer :-

$\boxed{\mathsf{x^{2}\:-\:25}}$
