Given the equation:
12x^4 - 42x^3 - 90x^2
Factor the given completely by finding the GCF.
Solution:
We can factor out 6x^2 from the given equation since 6x^2, is the greatest common factor.
= 12x^4 - 42x^3 - 90x^2
= 6x^2 ( 2x^2 - 7x - 15)
We are able to find 6x^2 since it is the common factor of 12, 42 and 90. Hence, since we do not have any other condition, then we have our final answer.
Final answer:
= 6x^2 ( 2x^2 - 7x - 15)
