Hello! And thank you for your question!

There are two formulas you can use to get the answer. Either the Quadratic Formula or Complete the square.

Today I will just be using the Quadratic Formula:

x = -b + √b²-4ac over 2a -b - √b²-4ac over 2a

x = 5 + √(-5)²+4 over 2 , 5 - √(-5)²+4 over 2

x = 5 + √29 over 2 , 5 - √29 over 2

Final Answer:

x = 5 + √29 over 2 , 5 - √29 over 2
