Find whether the following equations have real roots. If real roots exist, find them.
8x2 + 2x – 3 = 0
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,
