We will first start off by working through factoring quadratic expressions such as factoring out the GCF, difference of two squares, perfect square trinomials, and trinomials. We will then progress to solving by factoring where we have to apply the zero product property. Next we will work on solving quadratic equations that can not be factored by using completing the square as well as the quadratic formula. 3i/(-2+i)\n
