Solve each of the following quadratic equations:
9x2 + 6x + 1 = 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 = 9; b = 6; c = 1
= 9.1 = 9
And either of their sum or difference = b
= 6
Thus the two terms are 3 and 3
Sum = 3 + 3 = 6
Product = 3.3 = 9
Hence the equation has repeated roots
