Question

What is the nature of the roots of quadratic equation 4x² - 8 x + 9 = 0 ? *​

Answer 1

Answer:

Imaginary roots

Step-by-step explanation:

4x² - 8 x + 9 = 0

a=4; b=-8 ; c=9

discriminant value, b²-4ac = (-8)²-4(4)(9)

                                           = 64-16(9)

                                           = 64- 144

                                           = -80 <0

as the discriminant value is less than 0, the roots are imaginary
