Question

___(y - 5)^2___
y^2 - 25

Answer 1

Do you want to simplify it ?

Answer 2

multiply and simplify

Answer 3

First factor denominator using this formula
If we have a^2 - b^2 = (a - b)*(a + b)
Here at denominator we have y^2 - 25 = y^2 - 5^2 = (y-5)*(y+5)

Answer 4

SO at denominator we have got (y -5) * (y + 5)

So we get (y - 5)^2 / (y -5) * (y + 5)

Then just try to cancel common factor or same terms from numerator & denominator
So what do you get ?

Answer 5

Are u there ?

Answer 6

this might take a while

Answer 7

Have u understood ?

Answer 8

a little bit im taking online classes and im trying to understand the problems, i am not that good in math

Answer 9

Can you tell me which step u r not understanding ?

Answer 10

the elimination of the number like what you did on the top

Answer 11

oh is it because they are the same so you eliminate them both right?

Answer 12

Correct !!

Answer 13

Is it clear now ?

Answer 14

yes now i get it thank you

Answer 15

u r welcome :)

Answer 16

so the answer is ( y - 5) ( y+ 5)

Answer 17
