Factorize 1-V

^{2}

__Solution__
We use difference of two squares a

^{2}– b^{2}= (a - b)(a + b)
1-V

^{2}= 1^{2}-V^{2 }
= (1 - V)(1 + V)

**Hence 1 -**

**V**

^{2}

^{ }**= (1 -**

**V)(1 + V)**

__TRY THIS…………….__
Factorize 25 - W

^{2}^{}

^{}

Factorize 1-V^{2}

We use difference of two squares a^{2} –
b^{2} = (a - b)(a + b)

1-V^{2} = 1^{2}-V^{2 }

= (1 - V)(1 + V)

Factorize 25 - W^{2}
