(7v+6u) (7v-6u)
Simplify your answer.
(7v+6u)(7v-6u) = (7v)^2 - (6u)^2 = 49v^2 - 36u^2
SIMPLIFY YOUR ANSWER
The simplified answer is 49v^2 - 36u^2.
Clearly this is wrong
Apologies for the mistake. Let me correct it for you.
(7v+6u)(7v-6u) can be simplified using the difference of squares formula:
(a+b)(a-b) = a^2 - b^2
In this case, let a = 7v and b = 6u:
(7v+6u)(7v-6u) = (7v)^2 - (6u)^2 = 49v^2 - 36u^2
Therefore, the simplified answer is 49v^2 - 36u^2.

(v+8)(v-8)
Simplify your answer.
Using the difference of squares formula, (a+b)(a-b) = a^2 - b^2, we can simplify (v+8)(v-8) as follows:
Let a = v and b = 8:
(v+8)(v-8) = (v)^2 - (8)^2 = v^2 - 64
Therefore, the simplified answer is v^2 - 64.
