A. 1, -√10

B. 0, –10

C. 0, √10

D. 0, 10

A, B, C, or D? Please explain :)

Answer 1

c^2-10c=0

c(c-10) = 0

See where to go next?

Answer 2

No, I do not.

Answer 3

c(c-10) = 0

breaks up to

c = 0 or c-10 = 0

Answer 4

then what

Answer 5

I don't know. I'm not good at algebra.

Answer 6

solve c-10 = 0 for c

Answer 7

I don't know how.

Answer 8

something - 10 = 0

Answer 9

what number goes in the place of "something"

Answer 10

Important step:
If \[
a\cdot b=0
\]Then at least one of \(a, b\) must be zero.

Answer 11

10 - 10 = 0 @jim_thompson5910

Answer 12

so c-10 = 0 means that c = 10

Answer 13

so c = 0 or c = 10

Answer 14

So the answer is D?

Answer 15

yes

Answer 16

Ah, okay thank you :)
