Use the quadratic formula to find both solution to the quadratic equation given below 3x^2-7x-1=

The correct option is B  x= 7 ±÷ 6 .

Step-by-step explanation:

Given :  Quadratic equation -7x-1 = 0.

To find : Use the quadratic formula to find both solution to the quadratic equation.

Formula used : Quadratic formula a + bx + c =0 , where "a", "b", and "c" are just numbers  x= -b ±÷ 2a.

Explanation : Compare the a + bx + c =0 by  -7x-1 = 0.

a = 3 , b = -7 , c = -1 .

Plugging the values a,b,c in formula.

    x= -(-7) ±÷ 2*3.

   x= 7 ±÷ 6.

  x= 7 ±÷ 6.

Therefore, The correct option is B , x= 7 ±÷ 6.
