The next day Cleo went to take her math test and she was really nervous. The first question was to create and solve a quadratic function with 2 real zeros. She knew how to do this!
x=2 x-2=0
x=4 x-4=0
x(x-4)-2(x-4)
x^2-4x-2(x-4)
x^2-4x-2x+8
x^2+6x+8
Next she had to solve a system of non-linear equations with a graph:
