Q. 2 J

# Solve the following quadratic equations:  Given = 0

Recall that the roots of quadratic equation ax2 + bx + c = 0, where a ≠ 0, are given by Here, a = 1, and     By substituting i2 = –1 in the above equation, we get   We can write   [ i2 = –1]  [ (a – b)2 = a2 – 2ab + b2]

By using the result , we get     [ i2 = –1] Thus, the roots of the given equation are and .
