Question 44679
x2 – 3x – 3 -5= 5-5 [Set the equation equal to zero]
x^2 – 3x – 8 = 0
.
.
Plug the values of the coefficients into the quadratic formula:
a=+1
b=-3
c=-8
.
{{{x = (--3 +- sqrt( -3^2-4*1*-8 ))/(2*1) }}}
.
Simplify:
{{{x = (3 +- sqrt( 9 + 32 ))/(2) }}}
.
Continue to simplify:
{{{x = (3 +- sqrt( 41 ))/(2) }}}
.
.
x = 4.7015 or x = -1.7015
.
