solve by factoring: 6^ * 42x = 0

[Missy]

Would like to know if I have factored this correctly:

6^ *42x =0 With the 6^ I mean 6 squared
This is what I done
12 +42x =0
(x+6) (x+7) = 0
x+6-6=0-6 x+7-7=0-7
x+0=-6 x+0= -7
so x= -6 and x= -7
Can you tell me if I completed all the steps correctly or explain to me what I should do.

This is what I done
12 +42x =0 <-- 6^2 = 36 and where did "+" come from?
(x+6) (x+7) = 0 <-- How is that? If you multiply these out - do you get what you started with?
x+6-6=0-6 x+7-7=0-7
x+0=-6 x+0= -7
so x= -6 and x= -7

Your starting equation does not make sense - please correct it.

"six square" is written as "6^2"

"x square" is written as "6x^2"

"six times x square" is written as "6 * x^2"

Generally, " * " indicates " multiplication ".

Considering that the proper formatting was explained quite clearly in this thread, it was discouraging to see that you continued to use your made-up formatting in your various duplicate threads. It's almost as though you don't even read replies that don't give you the fully-worked solution to copy into your homework...?

Please read the replies you receive, and show some participation in the learning process. Thank you.
