30
Solve each of the following quadratic equations:
x2 + 3√3x – 30 = 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 = 1; b = 3√3 ;c = -30
= 1. - 30 = - 30
And either of their sum or difference = b
= 3√3
Thus, the two terms are 
Difference = 
Product = 
Hence the roots of equation are
