Question

Subtract the following polynomials.
1.(-12ab)-(25ab)
2.(12×+4y)- (5×3y)
3.(8ײ-5)-(6ײ+2×-10)
4.(15p-16r+21s)-(6p-9r+28s)
5.(40ab+7a²b²)-(9ab-11a²b²)

Pasagot plsss​

Answer 1

Answer:

1. -37ab

2. 7x + y

3. 2x² -2x +5

4. 9p -7r -7s

5. 31ab +18a²b²

Step-by-step explanation:

1. -12ab -25ab = -37ab

2. (12×+4y)- (5×3y)

= 12x -5x +4y -3y

= 7x +y

3. (8ײ-5)-(6ײ+2×-10)

= 8x² -6x² -5 +10 -2x

= 2x² -2x +5

4. (15p-16r+21s)-(6p-9r+28s)

= 15p -6p -16r +9r +21s -28s

= 9p -7r -7s

5. (40ab+7a²b²)-(9ab-11a²b²)

= 40ab -9ab +7a²b² +11a²b²

= 31ab +18a²b²

Hope this helps
