Question

Solve for x.
x^2 + 6x = 0

Answer 1

@skullpatrol gooooooo awayyy like seriously? stalk someone else's questions...

Answer 2

This question is done exactly the same way your previous questions were solved. What seems to be the problem? The method is exactly the same.

Answer 3

cool.

Answer 4

I'm sorry if you think I'm "stalking" you :(

Answer 5

Are you ready to learn @xcaseynoel ?

Answer 6

1. factor out the x.

Answer 7

Yes,
1. factor out the x
is the first step

Do you know why it works @xcaseynoel ?

Answer 8

-____-....meh... then solve for each x. yay the end.

Answer 9

is this just a regular problem or one of those complete the square problems? that's what I'm wondering.

Answer 10

Because of the distributive property of multiplication with respect to addition:
$$ab+ac=a(b+c)$$
$$x^2+6x= x(x+6)$$

Answer 11

\[(-6\pm6)/2\]
hence x=0 or x=-6

Answer 12

@xcaseynoel Does that make sense?

Answer 13

ok just the regular problem..if that's the case then solve for each x which is 0 and -6

Answer 14

x= (−6±6)/2
hence x=0 or x=-6

Answer 16

@skullpatrol see i used the formula for quadratic equation by which i was showing a better way to solve the question quickly. The factoring method here may take longer time and by this formula one can calculate such questions mentally.

Answer 17

@leena1996 but factoring is a valuable skill to learn how to do fast, no?

Answer 18

@skullpatrol Factoring is a good technique to learn but each question requires a different approach and some questions are not possible with factoring so one needs to apply other methods which can fetch them the answer without wasting time and learninig new techniques.
