Answer:
9x^2 -4
Step-by-step explanation:
(3x+2) (3x-2)
FOIL
first: 3x*3x = 9x^2
outer: 3x*-2 = -6x
inner: 3x*2 = 6x
last: -2*2 = -4
Add together
9x^2 -6x+6x -4
9x^2 -4
Answer:
they're not
Step-by-step explanation:
when you distribute the 2 into (x-3) you get 2x-6
and thats not equivalent to 2x-3
The answer is <span>A –x^2 + 3x + 15
</span>
3x² + 6 – 2x + 5x – 4x²<span> + 9
Rearrange it:
</span>3x² + 6 – 2x + 5x – 4x² + 9
= 3x² - 4x² - 2x + 5x + 6 + 9
= -x² + 3x + 15
