Solve x2 + 9x + 20 = 0.

x = 2, x = 10
x = -2, x = -10
x = -5, x = -4
x = 5, x = 4

So would it be D? @jdoe0001

studygurl14 · Answer

Actually, it would be C. Because using the information @jdoe0001 gave, you'd do this:
$\large (x+5)(x+4)=0$
Then split into two equations and solve for x
$\large x+5 = 0$ and $\large x+4=0$

Which would result in $\large x=-5,-4$
