what is the surd?
b^2-4ac
1-(-3*(-4)=1-12=0-11 which means in the quadratic equation
x= (-b +-sqrt(b^2-4ac))/2a
you have two complex solutions, ie
-+sqrt(-11) in the solutions.
zero real solutions.
Can you give me the steps to the answer?

Thank you but what does 'surd' mean?

You may be more familiar with the term "discriminant."
The discriminant is b^2-4ac, the value inside the square root symbol.
So, in this case, the surd being considered is the square root of the discriminant.

Yes, thanks.
