1) 4x + 8

Here , 4 is a common factor

4( x +2 ) are the factors .

------------------------------------------------------------

2) 8x^2 + 4x

Here , 4x is a common factor

= 4x( 2x +1) are the factors.

-------------------------------------------------------------

3) 3x^3 + 6x^2 + 9

Here, 3 is a common factor

= 3( x

are the factors.

-------------------------------------------------------------

1) 4x

Here first and last term are perfect square so we will use an identity of

a^{2} +2ab +b^{2} = ( a+b)^{2} |

(2x )

=(2x + 5)

Factors are (2x +5)(2x +5)

---------------------------------------------------------------

2) 9x

Here first and last term are perfect square so we will use an identity of

a^{2} -2ab +b^{2} = ( a-b)^{2} |

(3x )

=(3x - 1)

-------------------------------------------------------------------

3) a

a

= a

= (a

= (a

= (a - d)

= ( a - d + b - c)[a - d -(b - c)][ use a

= ( a - d + b - c)(a - d - b + c)

-----------------------------------------------------------------

4) a

a

= (a

= (a

= (a

= (a
