Question

Find the product of (4x − 3)(2x2 − 7x + 1).

8x3 − 22x2 + 17x− 3

8x3 + 8x2 + 4x − 3

8x3 − 34x2 + 25x − 3

8x3 − 42x2 + 25x − 3

Find the product of 2x4(4x2 + 3x + 1).

8x6 + 6x5 + 2x4

8x8 + 3x4 + 2x4

2x4 + 6x5 + 8x6

6x6 + 5x5 + 3x4



Which statement shows that when two polynomials 4x + 6 and 2x2 − 8x demonstrates the closure property when multiplied?

8x3 − 20x2 − 48x is a polynomial

8x3 − 20x2 + 48x may or may not be a polynomial

8x2 − 32x2 − 14x is a polynomial

8x3 − 32x2 + 14x may or may not be a polynomial

Could someone help me?

Answer 1

the first one is:
8x3 − 34x2 + 25x − 3

Answer 2

Thank you :) Could you help me with the other two?

Answer 3

the second is:
8x6 + 6x5 + 2x4
the last one is:
8x3 − 20x2 − 48x is a polynomial

Answer 4

Thank you so much, I really appreciate it! Could you help with just two more? If not I understand

Answer 5

sure

8x3 − 34x2 + 25x − 3

Answer 8

the second is:
x2 − 6x + 9

Answer 9

I'm sorry I meant this one, I pasted the same one twice.
Find the product of (x2 + 4x − 3)(2x2 + x + 6).

2x4 + 9x3 + 4x2 + 21x − 18

2x4 + 9x3 + 10x2 + 21x − 18

2x4 + 7x3 + 4x2 + 21x − 18

2x4 + 9x3 + 4x2 + 27x − 18
