Question

In algebra, is it possible for x to be equal to more than one answers?

Answer 1

Yep. For example:
\[
x^2=9
\]Here, \(x\) could equal:
\[
x=3, -3
\]Since:
\[
\text{If }x=3:(3)^2=9\\
\text{If }x=-3:(-3)^2=(-3)(-3)=9
\]Which are both true.

Answer 2

You mean is it possible for f(x) to be two different numbers for the same x? The answer is yes. For instance \[\sqrt{9}\] = +/- 3

Answer 3

like (x-10)(x+3)=0 , is it correct to say that x both equals 10 and -3?

Answer 4

Yep.

Answer 5

oh ok, thanks

Answer 6

Well, it doesn't EQUAL both of those, it's just that it *CAN* equal these, and these are solutions.

Answer 7

ok i see what your saying, thank ya :)
