Answer 1

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

Answer 2

It's definitely not C...

Answer 3

\((x^2 + 4x − 3)(2x^2 + x + 6)\)

Expand:

\(2x^4 + 9x^3 + 4x^2 + 21x - 18\)

Answer 4

Okay, just 2 more left

Answer 5

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

8x6 + 6x5 + 2x4

8x8 + 3x4 + 2x4

2x4 + 6x5 + 8x6

6x6 + 5x5 + 3x4

Answer 6

2x^4(4x^2 + 3x + 1) -- distribute through the parenthesis
8x^6 + 6x^5 + 2x^4

Its the first one

Answer 7

I have been abandoned xD

Answer 8

Thanks a ton @texaschic101 !!!

Answer 9

One more? :)

Answer 10

no problem :)

Answer 11

what ya got ?

Answer 12

Write a simplified polynomial expression in standard form to represent the area of the rectangle below.

A picture of a rectangle is shown with one side labeled as 5 x plus 2 and another side labeled as x minus 4.

5x2 + 18x − 2

5x2 + 13x + 2

5x2 − 18x − 8

5x2 + 13x + 8

Answer 13

A = L * W
A = (5x + 2) (x - 4) -- use the FOIL method
A = 5x^2 - 20x + 2x - 8 -- combine like terms
A = 5x^2 - 18x - 8
