Solve each of the following quadratic equations:
5x2 + 13x + 8 = 0
Using the splitting middle term - the middle term of the general equation 
is divided in two such values that:
Product = a.c
For the given equation a = 5; b = 13; c = 8
= 5.8 = 40
And either of their sum or difference = b
= 13
Thus the two terms are 5 and 8
Sum = 5 + 8 = 13
Product = 5.8 = 40
Hence the roots of equation are 
32
