So if someone could explain to me how to factor the following equation I would really appreciate it!....
x^2 - 7x = 0
Thank you!
x^2 - 7x = 0
Thank you!
-
x² - 7x = 0
You can see that x is a factor of both x² and -7x.
x² - 7x = x(x - 7) = 0
x = 0, 7
You can see that x is a factor of both x² and -7x.
x² - 7x = x(x - 7) = 0
x = 0, 7

Well, there are two terms having an x in it.
You can take out one x from both terms. You get:
x(x - 7) = 0
See for yourself, if you write the above equation out you will get x*x - 7*x = x^2 - 7x again.
x(x-7) = 0 has the solutions x = 0 or x = 7
Since if you fill in 0 for x, you will get 0. And if you fill in 7 the second part of the term will become zero and you get 0.
Hope this was what you were asking for?

Since it is already equal to 0, take out the greatest common factor from the left side.
you get:
x(x - 7) = 0
Now set each x equal to 0:
x = 0
and
x - 7 = 0
Now solve for x:
x = 0 and x = 7
you get:
x(x - 7) = 0
Now set each x equal to 0:
x = 0
and
x - 7 = 0
Now solve for x:
x = 0 and x = 7

First you take ut the common factor from the two terms:
x^2 - 7x = 0
x(x-7)=0
then x = 0 or x - 7 = 0 then x = 7
x^2 - 7x = 0
x(x-7)=0
then x = 0 or x - 7 = 0 then x = 7
-
x^2 - 7x = x(x-7)
x=0, 7
x=0, 7
-
x(x - 7) = 0
x = 0
x = 7
x = 0
x = 7
