use the quadratic formula to solve for x, 3x^2 + x -8=0
x = - b ± (sqrt(b^2 - 4ac))/2a
3x^2 + x - 8 = 0
a = 3, b = 1, c = -8

I really need help with my math/209 I took 208 3 years ago, and now I am taking the second part and I am so lost. How can I get some help.
To solve the quadratic equation 3x^2 + x - 8 = 0 using the quadratic formula, follow these steps:
Step 1: Identify the coefficients of the quadratic equation. In this case, a = 3, b = 1, and c = -8.
Step 2: Plug the values of a, b, and c into the quadratic formula:
x = (-b ± √(b^2 - 4ac)) / (2a)
Step 3: Substitute the values into the quadratic formula:
x = (-(1) ± √((1)^2 - 4(3)(-8))) / (2(3))
Step 4: Simplify the expression inside the square root:
x = (-1 ± √(1 + 96)) / 6
= (-1 ± √97) / 6
Therefore, the solutions for x are:
x = (-1 + √97) / 6
x = (-1 - √97) / 6
These are the two possible solutions to the equation 3x^2 + x - 8 = 0 using the quadratic formula.
