Use the discriminant to determine whether the following equations have solutions that are: two different rational solutions; two different irrational solutions; exactly one rational solution; or two different imaginary solutions. x^2=3x-6
In quadratic equation y=ax^2+bx+c
discriminate is D=b^2-4ac
In your case a=1 b= -3 c=6
When discriminante is negative quadratic have two imaginare solutions.
If you want to know that solutions in google type:
quadratic equation online
When you see list of results click on:
When page be open in rectacangle type:
and click option solve it
You will see solution step-by-step
