Answers:
(i) Every rhombus is a square.
This sentence is always false, because Rhombuses are not a square.
∴ It is a statement.
(ii) x2 + 5|x| + 6 = 0 has no real roots.
Let us take,
If x>0,
x2+5|x|+6=0
x2+5x+6=0
x = -3 or x = -2
x>0, the equation has no roots.
If x<0,
x2+5|x|+6=0
x2 – 5x+6=0
x<0, the equation has no real roots.
∴ It is a statement.
