Q. 1 A3.7( 19 Votes )

Find whether the following equations have real roots. If real roots exist, find them.

8x2 + 2x – 3 = 0

Answer :

To check whether the quadratic equation has real roots or not, we need to check the discriminant value i.e.,

D = b2 - 4ac

Given, 8x2 + 2x – 3 = 0

D = 22 - 4(8) (-3)

D = 4 + 96 > 0

Hence, the roots are real and distinct.

To find the roots, use the formula,
