4x^2+10x-2x-5
4x^2+8x-5
4x^2+10x-2x-5
2x(2x+5)-1(2x+5)
(2x+5)(2x-1)

RehanAhmadXLX: (2x + 5) (2x - 5)
Using identity.. (a + b) (a -b ) = a^2 - b^2
So, (2x + 5) (2x - 5) = (2x)^2 - 5^2

RehanAhmadXLX: = 4x^2 - 25

abhi875: in question doesnt follow that rule carefully watch

RehanAhmadXLX: Sorry not for this

RehanAhmadXLX: I dint see the Question properly
