Two real roots
Did you know?
WebIf asked for the exact answer (as usually happens) and the square roots can’t be easily simplified, keep the square roots in the answer, e.g. 2 − 10 2 \frac{2 - \sqrt{10}}{2} 2 2 − 1 … WebIf this is greater than 0, then we're going to have two real roots or two real solutions to this equation right here. If b squared minus 4ac is equal to 0, then this whole thing is just going to be equal to 0. It's going to be the plus or minus square root of 0, which is just 0. So it's plus or minus 0.
WebThe discriminant is less than zero, so there are two real roots. The discriminant is less than zero, so there are two complex roots.
