Answer 5

0,-30

Answer 6

These are my choices:

(−5, 0) and (6, 0)

(−5, 0) and (−6, 0)

(5, 0) and (−6, 0)

(5, 0) and (6, 0)

Answer 7

Answer 8

to get the x-intercept(s), take y =0

Answer 9

oops . . i was wrng
took x=0 instead :p

Answer 10

@RadEn i got C.. :)

Answer 11

30 = x^2 + x
subtract by 30 to both sides :
30-30 = x^2+x-30
x^2+x-30 = 0

factor out!
(x+6)(x-5) =0
for the zeroes, take each factor be equal zero
x+6=0, we have a solution x=-6

x-5=0, the solution is x=5

so, they are (-6,0)and (5,0)

Answer 12

yeah, it is C
