Factor this polynomial. -3x^2 - 16x - 5 A. (3x + 1) (x - 5) B. (3x - 1) (x - 5) C. -1 (3x + 1) (x + 5) D. (-3x + 1) (x + 5)

-(x + 5)(3x + 1)

Step-by-step explanation:

Step 1: Factor out negative

-1(3x² + 16x + 5)

Step 2: Factor quadratic

-(x + 5)(3x + 1)

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
