Multiply the following binomials. show your work.

(2x + 1)(x - 3)

In this question, you would multiply by using FOIL.

FOIL stands for First, Outside, Inside, Last.

Solve by using FOIL:

(2x + 1)(x - 3)

First: (2x)(x) = 2x²

Outside: (2x)(-3) = -6x

Inside: (1)(x) = x

Last: (1)(-3) = - 3

2x² - 6x + x - 3

Combine like terms:

2x² - 6x + x - 3

2x² - 5x - 3

2x² - 5x - 3

answer: ouch. thats difficult

step-by-step explanation:

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
