Question

2/x + 3/x-3 =1 Solve?? *sad face*

Answer 1

3/x-3 means 3/(x-3)?

Answer 2

or -3+3/x ?

Answer 3

the x-3 is the denominator

Answer 4

ok

Answer 5

2/x + 3/(x-3) =1
2x(x-3)/x+3x(x-3)/(x-3) = x(x-3)
2(x-3)+3x=x(x-3)
2x-6+3x=x^2-3x
x^2-8x+6=0
x^2-8x+6+10=10
x^2-8x+16=10
(x-4)^2 = 10
x-4 = √10 or x-4 = -√10
x= √10 +4 or x= -√10 +4

Answer 6

ok, thanks, wait a sec! i have three more, Please help me, i have only minutes left

Answer 7

\[x-2\sqrt{2x}=16\]

Answer 8

x-2√2√x-16=0
(√x)^2-2√2√x-16=0
(√x)^2-2√2√x+2-16=2
(√x-√2)^2=18
√x-√2=3√2 or √x-√2=-3√2
√x=4√2 or √x=-2√2
√x should be always positive.
so √x = 4√2
x = 32

Answer 9

:D thanks, ill be right back

Answer 10

x-2sqrt5x=15

Answer 11

\[x-2\sqrt{5x}=15\]

Answer 12

(√x)^2-2√5√x+5=15+5
(√x-√5)^2=20
√x-√5=2√5 or √x-√5=-2√5
√x=3√5 or √x=-√5
√x should be positive.
so, x = 45

Answer 13

okay thanks, can you help me with one more? i have three more left, but one should be enough :)
