Answer 1

Answer:

Step-by-step explanation:

Answer 2

Given:

⇒  $x^2-2x-3$

To Find:

Value of "x" = ?

Solution:

On factorizing the given equation, we get

⇒  $x^2-3x+x-3=0$

⇒  $x(x-3)+1(x-3)=0$

⇒  $(x+1)(x-3)=0$

⇒  $x+1=0$

⇒  $x=-1$

Or,

⇒  $x-3=0$

⇒  $x=3$

So that the correct answer will be "x = -1" and "x = 3".
