Solve Using The Quadratic Formula: X^2 - 3x - 23 = 5 Show Work?

The general quadratic equation is;

ax2 + bx + c= 0

The quadratic formula to solve the equation is;

x = [-b + (b2 - 4ac)1/2]/ 2a

The given quadratic equation is x2 - 3x - 23 = 5

x2 - 3x - 23 = 5

x2 - 3x - 23 -5 = 0

x2 - 3x - 28 = 0

By using quadratic formula;

x = [-*-3 + ((-3)2 - 4*1*-23)^1/2]/2

x = [3 +( 9 + 92)^1/2]/2

x = [3 + 101^1/2 ] / 2

x = [3 + 101^1/2 ] / 2 , [3 - 101^1/2]/2
