Question 296004
What is the first step in solving a quadratic equation?

A. Factor.
<pre>
Sometimes, but not always.

Not in this case:

{{{x^2+3x-7=0}}}

Since it is not factorable.  You'd begin by using the
quadratic formula, or completing the square.
</pre>
B. Get zero on one side of the equal sign.
<pre>
Sometimes, but not always.

Not in this case:

{{{(x-3)^2=25}}}

for you'd begin by taking square roots
</pre>

C. Set the factors equal to zero.
<pre>
Sometimes, but not always, certainly not when 
no factoring has been done, ofr if factoring is 
impossible.

</pre>
D. Each problem is solved differently
<pre>
That's the only one that you can count on!
