Alex17521 [72]

Answer:

A) Real Roots

B) Imaginary Roots

C) Equal Roots

D) Unequal Roots

E) Rational Roots

F) Irrational Roots

Step-by-step explanation:

The equation with one variable , in which the highest power of variable is two , is know as QUADRATIC EQUATION

ex - 3x² + 4x + 7 = 0

Every quadratic equation gives to values of unknown variables and these values is called roots of equation .

The quadratic equation have three roots :

A) Real Roots

B) Imaginary Roots

C) Equal Roots

D) Unequal Roots

E) Rational Roots

F) Irrational Roots

The nature of Roots depends entirely on the value of it Discriminant

If D = 0 ,  Roots are real and equal

If D > 0  , roots are real and unequal

If D <  0 ,roots are imaginary

where D = b² - 4ac for any quadratic equation ax² + bx + c = 0
