Answer:
C
Step-by-step explanation:
The greatest common factor and factoring by grouping of the following is;
- 3m
- 2a
- 8xy
- 5mn
- 3(r + t)²
- z²(m + n)⁴
<h3>Greatest common factor</h3>
The greatest common factor is the largest positive integer or polynomial that is a divisor of several different numbers. For instance, the greatest common divisor of 66, 30 and 18 is 6.
9m³, 3m², 15m
= 3m
4a², 6a, 2a³
= 2a
16xy³, 24x²y², 8x²y
= 8xy
10m²n², 25mn³, 50m²n
= 5mn
6m(r + t)², 3p(r + t)⁴
= 3(r + t)²
7z²(m + n)⁴, 9z³(m + n)^5
= z²(m + n)⁴
