Answer:
Step-by-step explanation:
Factor out the GCF of each term. It looks like as far as the coefficients go, you can factor out a 4 from each, but nothing greater than a 4. As far as the x-terms go, you can factor out x-squared from each, but nothing greater than that. Factoring out 4 x-squared:
[tex]4x^2(5x^2+2x+10)[/tex] which is the last choice there. You cannot factor the quadratic over the real number solutions, because there are none. They are both imaginary. So you're done!
