One root of the equation 3x2 - 10x + 3 = 0 is 1 . Find the other root. 3
-
- 3
-
1 3 - - 3
- None of these
Correct Option: A
The given quadratic equation is 3x2 - 10x + 3 = 0
Comparing with ax2 + bx + c = 0, we get
a = 3, b = −10, c = 3
∴ Sum of the roots ( k1 + k2 ) = - | = | ||
∵ One root k1 = | |
∴ The other root k2 = | - | = | = 3. | |||
Therefore , The other root is 3 .
