Question

find the discriminants of the equation 2x^2-5x-3=0 find the nature of its root . find them if they are real. (please help)​

Answer 1

it is quadratic equation so we used discriminate formula

-b+-under root b^2 -4 ac/2a

5+ - under root 25-40/4

5+- under root - 15/4

5+- under root -15/4

5+√-15/4 or 5-√-15/4
