First you must get everything on the left side thereby setting the equation equal to zero.
This is now in the proper form.
A = 5
B = 8
C = 3
Plug these values into the Quadratic formula
square 8
Multiply 4, 5 and 3
Multiply 2 and 5
Subtract 64 and 60
this is where it breaks into TWO problems
and
Square root 4 in both problems
and
work the Numerator in each fraction
and
Reduce the fractions
and
