(3x-2)(3x+ 2)
Multiply each term in one set of parentheses by the other terms:
3x x 3x =9x^2
3x x 2 = 6x
-2 x 3x = -6x
-2 x 2 = -4
Combine to get:
9x^2 + 6x - 6x -4
Combine like terms:
9x^2 - 4
The value of a would be 9.

Answer:
<em><u>38 15/16</u></em>
Step-by-step explanation:
39 + 1/8n
Since the n = -1/2, replace the 'n' in the original equation with that number
39 + 1/8 (-1/2)
Multiply numerator-to-numerator and denominator-to-denominator
1/8 times -1/2 equals -1/16
(Because a positive times a negative equals a negative)
Now your complete equation is:
39 + -1/16
Add those numbers together to get <u>38 15/16</u>
