The roots of the quadratic equation 7x² – 10x + 3 = 0 are:

Correct option is A

Given:

Quadratic equation: $$7x^2 - 10x + 3 = 0$$​​

Solution: 

​$$7x^2 - 10x + 3 = 0$$​

​$$7x^2 - 7x - 3x + 3 = 0$$​​

​$$(7x^2 - 7x) - (3x - 3) = 0$$​​

7x(x - 1) -3(x - 1) = 0

(7x - 3)(x - 1) = 0

x - 1 = 0  and  7x - 3 = 0

x = 1 and $$\frac{3}{7}$$​​
