You can solve quadratics a few diffrent ways, factoring is usually the easiest but not always possiable, completeing the square and the quadratic formula are others. For this problem you could use quadratic formula
x=-B+- sqrt(B^2–4*A*C)/2*A
x^2-5x-8=0 here A would equal 1,B=-5,C=-8
just plug and chug the equation you will have two answers due to the + and – in the numerator.
I think the ans is – and +3.82 I dont have a calculator in front of me but that should be very close.
