Given expressions are
3x² + 3x - 5 , 2x² - 8x - 5
i ) Subtracting first expression
from second expression
2x² - 8x - 5 - ( 3x² + 3x - 5 )
= 2x² - 8x - 5 - 3x² - 3x + 5
= 2x² - 3x² - 8x - 3x - 5 + 5
= -x² - 11x
ii ) subtracting second expression
from first expression, we get
3x² + 3x -5 - ( 2x² - 8x - 5 )
= 3x² + 3x - 5 - 2x² + 8x + 5
= 3x² - 2x² + 3x + 8x - 5 + 5
= x² + 11x
