Let the required answer be " x "
a³ - 4a² + 5 - x = a² - 2a + 1
a³ - 4a² + 5 - (a² - 2a + 1 ) =x
a³ - 4a² + 5 - a² + 2a - 1 ) =x
a³ + a² ( -4 - 1 ) + a ( 2 ) + 1 ( 5 - 1) = x
a³ -5a² + 2a -4 = x.
Therefore the required solution is a³ -5a² + 2a -4 .
a³ - 4a² + 5 - x = a² - 2a + 1
a³ - 4a² + 5 - (a² - 2a + 1 ) =x
a³ - 4a² + 5 - a² + 2a - 1 ) =x
a³ + a² ( -4 - 1 ) + a ( 2 ) + 1 ( 5 - 1) = x
a³ -5a² + 2a -4 = x.
Therefore the required solution is a³ -5a² + 2a -4 .
