Question

(x-5)²-(x-2)²=-2
answer it

​

Answer 1

Step-by-step explanation:

Hi ,

( x/2 - 2/5 )( 2/5 - x/2 ) - x

= - ( x/2 - 2/5 )( x/2 - 2/5 ) - x

= - ( x/2 - 2/5 )² - x

= - [( x/2 )²+( 2/5 )²-2 × x/2 × 2/5]-x

= -[ x²/4+4/25-2x/5 ] - x

= -x²/4 + 2x/5 - 4/25 - x

= -x²/4 + ( 2/5 - 1 )x - 4/25

= -x²/4 +[ (2 - 5 )/5]x - 4/25

= -x²/4 - 3x/5 - 4/25

I hope this helps you.
