Question

Find the zeros of the function: 8c^2=4c

Answer 1

1. Subtract 4c from both sides.
2. Factor
3. Set each factor equal to 0
4. Solve each equation.

Answer 2

im sorry im still confused

Answer 3

@ineedyouubiebs what he meant to say was

8c^2 - 4c = 4c - 4c

so 8c^2 - 4c = 0

Factorise this expression.

Answer 4

@luckythebest so would it be 4c(2c-c) ????????

Answer 5

@ineedyouubiebs not really

It will be 8c^2-4c = 0

4c(2c - 1) = 0 , and not 2c-c

Answer 6

and my next step would be what?

Answer 7

Set each factor equal to 0

Answer 8

@luckythebest no what you said was true

Answer 9

@ineedyouubiebs if 4c(2c-1) = 0, then one of these two will be 0.

4c = 0 or 2c-1 = 0.

Answer 10

so then my final answer would just be 0 and 0?

Answer 11

@ineedyouubiebs nope.

we have two equations whose solution is 0.

so 4c = 0 and 2c-1 = 0

i.e. c = 0/4 or 2c = 1. accordingly solve for c. :)
