This video is describing how to solve quadratic equation by quadratic formula. The quadratic equation is given in the video and we will use quadratic formula. We will put the equation in the formula our equation is 4psquare= -23p - 15. Now add 23 to both sides and then add 15 to both sides now we will get an easy equation, 4 will be used as a and 23 will be used as b and 15 will be used as c and we have a=4,b=23 and c=15 put these values in the quadratic formula and we have the value of p=5.-3/4 thats all.
