    Answer:

    Roots are real and positive

    Step-by-step explanation:

    (b²-4ac) define the nature of roots.

    2x²+7x+3 =0

    Comparing with standard quadratic equation ax²+bx+c =0

    Here, a=2 , b=7 , c=3

    Therefore,

    b²-4ac

    = (7)²- 4(2)(3)

    = 49 – 24

    = 25 > 0

    => b²-4ac >0

    => Roots are real and positive.
