Question

HELP ME

Answer 1

\[\sqrt{5X+1}-\sqrt{X}=5?\]

Answer 2

NEED SOLUTION solve for x

Answer 3

\[\sqrt{5x+1}=5+\sqrt{X}\]

Answer 4

1) add sqrt(x) on both sides

2) Squaring both sides

Answer 5

ready

Answer 6

What ?

Answer 7

ready , set , go!

Answer 8

ll be 5x+1=25+x

Answer 9

No Use (a+b)^2=a^2+2ab+b^2

Answer 10

okay ll be 5x+1=(5+\[\sqrt{x}\])^2

Answer 11

Now use the formula ?

Answer 12

\[5x+1=(5+\sqrt{x})^2\]

Answer 13

im i r8?@hba

Answer 14

Yes but now use


(a+b)^2=a^2+2ab+b^2

what will

[5+sqrt(x)]^2 be ?

Answer 15

ll be \[(5+\sqrt{x})^2=25+10\sqrt{x}+x\]

Answer 16

Put it in your question now.

Answer 17

ll be\[5x+1=25+10\sqrt{x}+x\]

Answer 18

then bro?

Answer 19

\[5x-x=25-1+10\sqrt{x}\]

Answer 20

\[4x=24+10\sqrt{x}\]

Answer 21

then?

Answer 22

4x-24=10sqrt(x)

2(2x-12)=10sqrt(x)

2x-12=10sqrt(x)/2

2x-12=5sqrt(x)

Now Use Squaring both sides again.

Answer 23

\[(2x-12)^2=5\]

Answer 24

\[4x^2+48x+144=5\]

Answer 25

\[4x^2+48x+139=0\]

Answer 26

can we use\[x=(-b \pm \sqrt{b^2-4ac})/2a?\]

Answer 27

Now use Quad formula

or

Breaking the middle term

or

Completing the square method

Answer 28

Yes you can use Quad formula :)

Answer 29

No don't be lazy :/

Answer 30

@mustry

Start working.

Answer 31

\[x=(-48\pm \sqrt{2304-2224})/8\]

Answer 32

\[x=(-48\pm \sqrt{80})/8\]

Answer 33

I guess you can simplify it further

Answer 34

@mustry

I guess you are done :P

Answer 35

\[x=(-48\pm8.9)/8\]

Answer 36

the answer have been given to be either 0 or 16

Answer 37

when u put 16 u ll get correct but how can we get it please

Answer 38

I can only instruct you :/

Answer 39

okay
