Answer:
49m^4 - 25
Step-by-step explanation:
The simpler expression can simply be found by expanding
The kind of expansion we have here is the difference of two squares
(a + b)(a-b) = a^2 - b^2
Thus, we have it that;
(7m^2-5)(7m^2 + 5)
=
49m^4 - 25
It is equivalent to 7(6) + 14
Step-by-step explanation:
- Step 1: Solve 7(a + 2) when a = 6
⇒ 7 (6 + 2) = 7 × 8 = 56
- Step 2: Find its equivalent
7(6) + 14 = 42 + 14 = 56
11/12 because it is more than 1/2 (which is what 4/8 simplifies to!)
Answer:
