# State whether the following quadratic equations have two distinct real roots. Justify your answer. 2x2-32x+12 = 0 - Mathematics

Sum

sqrt(2)x^2 - 3/sqrt(2)x + 1/sqrt(2) = 0

#### Solution

The equation sqrt(2)x^2 - 3/sqrt(2)x + 1/sqrt(2) = 0 has two real and distinct roots.

D = b2 – 4ac

= (-3/sqrt(2))^2 - 4(sqrt(2))(1/2)

= (9/2) - 2sqrt(2) > 0

Hence, the roots are real and distinct.
