Factors of x2 plus 6x plus 16?

Answer 1

(X² + 6x + 16) Since the 6 is positive, you want to find two number that multiply to get 16 and add to get 6. There are none.

You need the quadratic formula: (-b±√(b²-4ac))/2a

(-6±√(36-48))/2

(-6+√-12)/2 (-6-√-12)/2

-3+6i and -3-6i

Both are imaginary numbers, so there are no real solutions. ■
