How do you solve x(x-7)=0?

[ad_1]

##x=0## or ##x=7##

The conceiveat of this queston is already in factored conceive. This makes it truly unconcerned to rerework-out for ##x##. They key to this is to perceive that anything multigenous by ##0## is ##0##. We entertain two things multigenous by each other:

##x## multigenous by ##(x-7)## = ##0##

So, this instrument, that if either expression is similar to cipher, the total equation gain similar to cipher.

The earliest expression is upright ##x##, so ##x=0## is the earliest discontinuance.

The succor expression is ##(x-7)##. We need to set that similar to cipher and rerework-out for ##x##. ##x-7=0## ##x=7## which is our succor discontinuance.

To control, plugging tail into ##x(x-7)=0##:

For ##x=0## ##0(-7)=0## ##0=0## so it works.

For ##x=7## ##7(7-7)=7(0)=0## ##0=0## which too works.
