Question

50x² – 2(x - 2)² factorise it
​

Answer 1

Answer:

Step-by-step explanation:

$50x^{2} - 2(x-2)^{2}$

= 2 [ $25x^{2} -(x-2)^{2}$  ( taking 2 common)

= 2 $(5x)^{2} - (x-2)^{2}$

= 2(5x + x - 2) (5x - x + 2 )  [ using identity $a^{2} - b^{2} = (a-b) (a+b)$ ]

= 2(6x - 2) ( 4x - 2)

= 2 *2 [ (3x - 1) ( 2x - 1) ]

= 4 ( 3x - 1 ) ( 2x - 1 )

Answer 2

Step-by-step explanation:

50x²-2(x-2)²

=50x²-2x-8

→50x²-2x-8=0

→50x²-2x=8

→48x=8

→x=8/48

→x=1/6
