Answer:

x=6.54138

x=0.458619

Step-by-step explanation:

using the Quadratic Formula where

a = 1, b = -7, and c = 3

x=−b±[tex]\sqrt{b^{2} -4ac}[/tex]/2a

x=−(−7)±√[(−7)2−4(1)(3)]/2(2)

x=7±√(49−12)/2

x=7±√37/2

The discriminant b2−4ac>0

so, there are two real roots.

Cannot Simplify the Radical:

x=[tex]\frac{7+-\\\sqrt{37} }{2}[/tex]

which becomes

x=6.54138

x=0.458619
