Question 1052778
.
For each equation 1 - 4 you must:


<pre>
1.   To write it in the general form {{{ax^2 + bx + c}}} = 0.


2.  To calculate the discriminant D = {{{b^2 - 4ac}}}.


3.  If D > 0 then the equation has two different real roots.

    If D = 0, then the equation has only one real root.

    If D < 0, then the equation does not have real roots.
              Instead, it has two complex roots.
</pre>

Do not try to shift your work to our shoulders.
Do it yourself.


Do not forget to send "Thank you" to me for clear instructions.



And the last note: what you called "determinant" in your post, is actually "discriminant".


Use math terms correctly.
