Do you know the formula for the discriminant?

anonymous · Answer

lol no im completely lost in this question

lncognlto · Answer

:) ok it is $$b ^{2} - 4ac$$ from when the equation is in the form ax^2 + bx + c = 0.

lncognlto · Answer

If the discriminant = 0, then the roots of the equations are x = $$\pm b \div 2a$$. If it is positive, the roots are unequal, x = $$(-b \pm \sqrt{(b ^{2} - 4ac)} ) \div 2a$$. If it is negative, there are no real roots of the equation.
