Question

Solve this quadratic equation using the quadratic formula. 3x^2 + 5x + 1 = 0

Answer 1

The solutions to the equation are
`(-5 +/- √(13))/(6)`

You can find the answer to any quadratic by using the quadratic formula. The formula is below.

`\frac{-b +/- \sqrt{b^(2)-4ac}}{2a}`

Then find a (the number attached to x^2), b (the number attached to x) and c (the constant). This will allow you to plug in and solve.

`\frac{-5 +/- \sqrt{5^(2)-4(3)(1)}}{2(3)}`

`(-5 +/- √(25-12))/(6)`

`(-5 +/- √(13))/(6)`
