The completing square method gives two distinct solutions
C. False.
We can use completing the square method if there is any constant term
example. x² + 4x =0
add 4 on both sides
x² + 4x + 4 = 4
(x +2)² = 2²
x + 1 = ±2
x = +2-1 =1 or x = -2-1 = -3
D.True.
If we know the value of coefficient of x then only we can use completing square method
