QUESTION ;

what should be subtracted from 1 + x - x² to get 2x + x ²

Given terms are ;

• 1 + x - x²
• 2x + x²

METHOD TO SOLVE :

By equation method and by letting the result as "a"

SOLUTION OF QUESTION ;

LET , THE AMOUNT BE X

so,

( 1 + x - x² ) - a = 2x + x²

1 + x - x² - ( 2x + x²) = a

1 + x - x² - 2x - x² = a

1 - x - 2x² = a

HENCE,

1 - X - 2X² SHOULD BE SUBTRACTED FROM 1 + X - X² TO GET 2X + X²
