Question

16y=20y^2

Answer 1

Subtract 16y on both sides
giving you
\[16y-16y=20y^2-16y\]
\[0=20y^2-16y\]
\[\text{You need to factor the right hand side: } 20y^2-16y \text{ <---the side with this expression}\]

Answer 2

Thank you!! So the answer is 0=(4y)(5y-4) Correct??

Answer 3

Then set both factors =0 :)

Answer 4

When does 4y=0 when y=?
When does 5y-4=0 when y=?

Answer 5

so y= 0, 5/4

Answer 6

flip 5/4

Answer 7

Do you see why?

Answer 8

\[5y-4=0 \text{ add 4 on both sides }\]

Answer 9

then divide both sides by 5 (5 will therefore be on the bottom )

Answer 10

Got it!!! Thanks so so much!!
