1.	If `ax^2 + bx + c = 0` is satisfied by every real value of x, then
Answer» Let `y = ax^2+bx+c` So, with the given equation,`ax^2+bx+c = 0` `y = 0` If we draw this, it will be a straight line along `X`-axis.It means, ` c = 0` For, any real value of `x`, `ax^2+bx` will be `0`, only when `a = b = 0` So, `a = b = c = 0` So, option `(c)` is the correct option.
