The zeroes are
Explanation:
I'm assuming that you mean how to find the zeroes of the function. First, factor out the
Now, set each of these factors equal to zero and see what
The results are
You don't. You can solve for the "roots" of the equation or find a "y" for a given "x". But "x" is a continuous variable.
The roots are
Explanation:
"Solving an equation means either generating a dependent value (y) from an independent value (x) or finding its "roots" - those values of "x" which generate a "y" value of zero (0). You cannot "solve" for an independent variable.
To find the roots, you can rearrange the expression:
From the second expression you can see that a value of
