Hey there!
This equation is in standard form, which is .
We are going to solve this with the quadratic equation, so we need to find the values for a, b, and c in the given equation. We can just look at it and identify the variables.
a = 3, b = 1, c = -5
Let's plug these values into the quadratic equation:
Multiply 4(3)(-5) together and multiply 2(3). Square 1.
Add 1 and 60.
This is our answer in exact form. If you need this as an approximate value, let me know and I will do that for you.
Hope this helps!
