Question

what is the nature of the roots of the quadracti equation 4
$x { - 8x + 9 = 0}^{2}$
​

Answer 1

Answer:

Answer:

NO REAL ROOTS.

Step-by-step explanation:

4x² - 8x + 9 = 0

quadraric equation is in the form of

ax²+bx+c = 0

To find the nature of roots, we have to find

D = b² - 4ac

D = (8)² - 4(4)(9)

= 64 - 144

= - 80

D < 0 ; it has no real roots.

NATURE OF ROOTS :

If D < 0 ; no real roots.

If D = 0 ; real and equal roots.

If D > 0 ; real and unequal roots.
