SUBTRACTING POLYNOMIALS

QUESTION

1. (5a+4) - (3a+1) = ?

  • change the sign of the subtrahend and proceed to addition

= 5a+4 + (-3a -1)

  • combine like terms

= (5a - 3a) + (4-1)

= 2a + 3

2. (-2x - 4) - (2x + 4) = ?

= (-2x - 4) - (2x+4)

  • change the sign of the subtrahend and proceed to addition

= (-2x-4) + (-2x-4)

  • combine like terms

= (-2x-2x) + (-4-4)

= (-4x) + (-8)

= -4x-8

ANSWER

1. 2a+3

2. -4x-8
