Answer 2

Step-by-step explanation:

Given : ( 5 P - 1 ) ^2

Find :

Expand Form

Using Some Identities To Solve These Questions

( a - b ) ^ 2 = a^2 + b^2 - 2ab

Putting Value To Formula

( 5p - 1 ) ^2 = ( 5p ) ^2 + ( 1 ) ^2 - 2 ( 5p ) ( 1 )

= 25p^2 + 1 - 10p

= 25p^2 - 10p + 1

Here The Answer is 25p^2 - 10p + 1

Some Important Identities Are :

• ( a + b ) ^ 2 = a^2 + b^2 + 2ab
• ( a - b ) ^2 = a^2 + b^2 -2ab
• ( a^2 - b^2 ) = ( a + b ) ( a - b )
• ( a^3 + b ^3 ) = ( a + b ) ( a^2 - ab + b^2 )
• ( a^3 - b^2 ) = ( a - b ) ( a^2 + ab + b^2 )
• If a + b + c = 0 , then a^3 + b^3 + c^3 = 3abc
