Question

Quadratic equations

Answer 1

I didn't get it

Answer 2

what did you do

Answer 3

Let the common root be lambda
After i used the cross multiplication method and got lambda to be 1/2

Answer 4

let \(\lambda \) be the common
\(a\lambda^2 +2c\lambda+ b= a\lambda^2 +2b\lambda +c =0 \)

Answer 5

Ok

Answer 6

Did you do the cross multiplication correctly ?

Answer 7

Yes

Answer 8

@ikram002p and it is given b is not equal to c

Answer 9

First of all cancel a(lambda)^2

Answer 10

ax^2 +2cx + b= 0

ax^2 +2bx +c =0
have a common root then b is not equal to c

a+4b+4c = 0

Answer 11

and yes lambda = 1/2 is right

Answer 12

Now, multiply 4 on both sides in this equation:

ax^2 + 2bx + c = 0 and then put x = lambda = 1/2

Answer 13

s0

\( 2\lambda (c-b) - (c-b) =0 \)

Answer 14

ohk u did that already :D

Answer 15

where the rest of the Qn lol

Answer 16

0.25a + b +c = 0

Answer 17

Multiply by 4 both sides.

Answer 18

what was the thing u wanted to prove ?

Answer 19

Not to prove anything

Answer 20

a +4b + 4c =0

Answer 21

ohk ^^

Answer 22

a + 4(b+c) = 0

Answer 23

@No.name You will get this expression after multiplying by 4 on both sides in the last equation you wrote.

Answer 24

Wait

Answer 25

0.25a +c + b = 0

4a +4(b+c) = 0

Answer 26

Yeah i am getting it @vishweshshrimali5

Answer 27

^

Answer 28

Good

Answer 29

How would that lead us to the answer

Answer 30

Can you please repost your question ? I don't know the part after that.

Answer 31

Okay

Answer 32

I meant the part of the question ;)

Answer 33

But, you already proved this part.

Answer 34

ohk then what T_T
u showed that already :'(

Answer 35

ax^2 +2cx + b= 0
ax^2 +2bx +c =0

have a common root then b is not equal to c

Find
a+4b+4c =

Answer 36

But, you found out that its equal to zero, already.

Answer 37

I didn't

Answer 38

No.name Human Calculator


0.25a +c + b = 0
4a/4 +4(b+c) = 0

Answer 39

It is

Answer 40

Oh yes

Answer 41

(:

Answer 42

There you have it :)

Answer 43

Yeah lol we proved it

Answer 44

sorruy

Answer 45
