Question

Factor each polynomial. Write prime if it is not factorable. Check your answer.

1.49m²-27m⁴+49m²-7
2.12c³d-15c²d+3cd

Answer 1

#1. Combining the m^2 terms, you have
98m^2 - 27m^4 - 7
If you let u = m^2, that's
-(27u^2-98u+7)
Since the discriminant is not a perfect square, it will not factor

#2. 3cd is clearly a common factor, so
3cd(4c^2 - 5c + 1)
You should be able to factor that.
