What are the solutions to this quadratic equation x2+6x-5=0
marishachu [46]

Answer:

See Below.

Explanation:

Quadratic Form:

a {x}^{2}  + bx + c

Quadratic Formula:

x =  \frac{ - b +   -  \sqrt{ {b}^{2}  - 4ac} }{2a}

Based on the information given from the question, we can deduce:

a = 1

b = 6

c = -5

Now we can substitute all these values into the formula to find x.

x =   \frac{ - 6 +  -  \sqrt{ {6}^{2}  - 4(1)( - 5)} }{2(1)}  \\  =   - 3 +  \sqrt{14}   \: or \:  - 3 -  \sqrt{14}
