Question

4. What is y = (3x – 9)(x + 2) in standard
form?
A y = 3x² - 4x - 18
B y = 3x - 3x - 18
Cy= 3x2 - 6x + 6

Answer 1

Answer:

B)y = 3x^2 - 3x-18

Step-by-step explanation:

y = (3x – 9)(x + 2)

y = 3x*x+3x*2-9*x-9*2

y = 3x^2 +6x-9x-18

y = 3x^2 - 3x-18

Answer 2

Answer: It is B

It is hard to explain online, but I know it is the right answer.
