Question

X2+2x-15=0
Find the quadratic formula

Answer 1

Explanation:

For a quadtratic in the form of

`ax^(2) + bx + c = 0`

The solutions to this can be found using the quadratic formula:

`x = \frac{-b \pm \sqrt{b^(2) - 4ac}}{2a}`

For the given equation,
`a = 1`,
`b = 2`,
`c = -15`. Plugging these numbers into the formula will give you the answer.
