A quadratic equation of the form 0 ax2 bx c

Asked by maham237 @ 15/07/2021 in Mathematics viewed by 450 People

has a discriminant value of –16. How many real number solutions does the equation have?

Answered by maham237 @ 15/07/2021

The discriminant of a quadratic is given as $b^2 - 4ac$ , so we know that $b^2 - 4ac = -16.$

When using the quadratic formula to calculate values for $x$ , we have to take the root of the discriminant. There is no real answer to the root of a negative number and so the equation has no real roots.
