Question

PLEASE HELP!!!

What is the simplified form of 5/3y+2 - 4/9y^2-4

Answer 1

a) 15y-6/(3y-2)(3y+2)
b) 15y-6/(3y+2)(3y+2)
c) 15y-14/(3y+2)(3y-2)
d) 15y-14/(3y+2)(3y+2)

Answer 2

9y^2-2 = (3y-2)(3y+2)

so

5/3y+2 - 4/9y^2-4 = 5/(3y+2) - 4/((3y+2)(3y-2))
so we multiply the left by (3y-2) on top and bottom so that we can have a common denominator
(5(3y-2)-4)/((3y-2)(3y+2))

Answer 3

can you simplify?

Answer 4

just simplify the top 5(3y-2)-4

Answer 5

@danny562 ?

Answer 6

you should participate :)

Answer 7

@zzr0ck3r ATTENTION !!! in your first answer there need being -4 and not -2 !!!

ok ?

correct it please !!!

Answer 8

right 9y^2-4 = (3y)^2-2^2 = (3y-2)(3y+2)

Answer 9

@danny562 so do you understand it ,can you solve it now ?

Answer 10

so just continue it with this

5(3y-2)-4 = ?

Answer 11

so = 15y-10 -4 = 15y -14

and for denominator will be (3y-2)(3y+2)

so if you check these choises you see what will be right ...

ok ?

wait your answer ---

Answer 12

are you here ?

Answer 13

Answer 15

are you here now ?

Answer 16

5/3y+2-4/9y^2-4
or,5/3y+2-4/3y^2-2^2
or,5/3y+2-4/(3y+2)(3y-2)
or,5(3y-2)-4/(3y+2)(3y-2)
or,15y-10-4/(3y+2)(3y-2)
or15y-14/(3y+2)(3y-2)

Answer 17

@Spynextdoor ATTENTION !!! in the second line the denominator of second fraction so not is right you have missed there an parentheses not is just y squared the 3 is squared too

ok ?
