When I expand your choice of answer, I get
x^2 - 11x + 30, so clearly not the right answer.

you can tell from the -30, that the two constants must be of opposite sign, ruling out A and C
Try expanding the other two
Its C @Reiny
No, Evan, I thought we had ruled out C

Did you expand C before you decided?

for C: (x+6)(x+5)
= x^2 + 5x + 6x + 30
= x^2 + 11x + 30, not the given expression

for B:
(x+6)(x-5)
= x^2 - 5x + 6x - 30
= x^2 + x - 30 , the given!!
ohhh so its B @Reiny
Guys, its still correct! PogChamp is now illegal so pls dont call the cops on me
. cool
cool indeed, "Jamal did it".
