Question

if b²-4ac>0, then the quadratic equation ax²+bx+c=0 has
two distinct real roots
two equal real roots
no real roots
two square roots​

Answer 1

Answer:

If b2 -4ac> 0,then equation will have two distinct real roots. 2. In quadratic equation ax2 + bx + c = 0, b2 -4ac is known as Discriminant. ... The nature of roots of quadratic equation x2 -5x-7 = 0 are real and equal.

Answer 2

Answer:

Given an equation in a single variable, a root is a value that can be substituted for the variable in order that the equation holds. In other words it is a "solution" of the equation. It is called a real root if it is also a real number. For example: x2−2=0.
