OPPGAVE 4

a) solve equation by using abc-formula x2 + 3x + 2 = 0

b) solve the equation by calkulater x2 - 2x +1 = -x +1

When is this due? What have you tried? Where are you stuck? What is abc formula?

I think atomsa is referring to the quadratic equation

for

the solutions are given by



in this case a=1,b=3,c=2 so
