Answer 1

To solve the quadratic equation 3x^2 - 7x - 6 = 0 using the quadratic formula, we first identify the values of a, b, and c:

a = 3
b = -7
c = -6

The quadratic formula states that the solutions for the equation ax^2 + bx + c = 0 are given by:

x = (-b ± √(b^2 - 4ac)) / 2a

Plugging in the values for a, b, and c:

x = (7 ± √((-7)^2 - 4*3*(-6))) / 2*3
x = (7 ± √(49 + 72)) / 6
x = (7 ± √121) / 6
x = (7 ± 11) / 6

Therefore, the solutions are:

x = (7 + 11) / 6 = 18 / 6 = 3
x = (7 - 11) / 6 = -4 / 6 = -2/3

So, the correct answer is x = 3, x = -2/3.
