Let
f%28x%29=x%5E2%2B3x%E2%88%9213, and g%28x%29=-3
Find all values for the variable x, for which
f%28x%29=g%28x%29
x%5E2%2B3x-13=-3
x%5E2%2B3x-13%2B3=0
x%5E2%2B3x-10=0..........factor
x%5E2%2B5x-2x-10=0
%28x%5E2%2B5x%29-%282x%2B10%29=0
x%28x%2B5%29-2%28x%2B5%29=0
%28x+-+2%29+%28x+%2B+5%29+=+0

solutions: x=2 or x=-5
