Mark as BRAINLEST

Step-by-step explanation:

2x2 – 8x + 5 = 0 Compare given equation with the general form of quadratic equation, which is ax2 + bx + c = 0 a = 2, b = – 8, c = 5 Using Discriminant Formula: D = b2 – 4ac = (– 8)2 – 4 x 2 x 5 = 64 – 40 = 24 > 0 Hence the roots of equation are real and unequal.Read more on Sarthaks.com - https://www.sarthaks.com/704451/find-the-nature-of-the-roots-of-thequadratic-equation-2x-2-8x-5-0
