Check whether the equation 8x2+ 2x – 3 = 0 has real roots, and if it

1.	Check whether the equation 8x2+ 2x – 3 = 0 has real roots, and if it has, find them.
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,

Check whether the equation 8x2+ 2x – 3 = 0 has real roots, and if it has, find them.

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,
