Question

a^2=2a
find a

Answer 1

Are you looking for a point?

Answer 2

\[\large{a^2 = 2a}\]
\[\large{\implies a^2 -2a = 0}\]
\[\large{\implies a(a-2) = 0}\]
\[\large{ a = 0 ~~\text{or}~~ a = 2}\]

Answer 3

a=0,2

Answer 4

a^2-2a=0
a(a-2)=0

Answer 5

a=2,0

Answer 6

See @manojji;

If we have :

\[\large{xy = 0}\]

Then, it means either x = 0 or y = 0.

Now, first I factorised the given expression into product of two expressions, so that I can solve it more easily.

Answer 7

For example, lets see another one:

\[\large{a^2 = 3a - 2}\]

Can you solve this one ?

Answer 8

\[a ^{2}-2a-a+2\]
(a-2) (a-1)
