Answer 1

Step-by-step explanation:

4 number ka answer ye hai

Answer 2

Step-by-step explanation:

4) 12m^2-27

=> 3(4m^2-9)

=> 3[(2m)^2-(3)^2]

=> 3(2m+3)(2m-3)

5)125x^5-45y^2

=> 5(25x^2-9y^2)

=> 5[(5x)^2-(3y)^2]

=>5(5x+3y)(5x-3y)

6)144a^2-169b^2

=> (12a)^2-(13b)^2

=>( 12a+13b)(12a-13b)

7)(2a-b)^2-16c^2

=> (2a-b)^2-(4c)^2

=> (2a-b+4c)(2a-b-4c)

8)(x+2y)^2-4(2x-y)^2

=> (x+2y)^2-[2(2x-y)]^2

=> (x+2y+4x-2y)(x+2y-4x+2y)

=> (5x)(4y-3x)

9)3a^5-48a^3

=> 3a^3(a^2-16)

=> 3a^3(a^2-4^2)

=> 3a^3(a+4)(a-4)
