All quadratic equations can be solved by the quadratic equation which is x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
Lets start by defining a, b, and c
a=1
b=-4
c=-32
Now we substitute the variables for the numbers and solve the equation
x=-%28-4%29%2Bsqrt%28%28-4%29%5E2-4%2A1%2A-32%29%29%2F%282%2A1%29+ and x=-%28-4%29-sqrt%28%28-4%29%5E2-4%2A1%2A-32%29%29%2F%282%2A1%29+
Simply both equations
x=%284%2B12%29%2F2 and x=%284-12%29%2F2
x=16%2F2 and x=-8%2F2
x=8 and -4
