Write the discriminant of the following
(P)
(i) \( 3 x^{2}-4 x+7=0 \)
(ii) \( \sqrt{3} x^{2}-2 \sqrt{2} x-2 \sqrt{3}=0 \)
(iii) \( 2 x^{2}+3 x+m=0 \)
(iv) \( x^{2}+x+7=0 \)
(v) \( (4 x-3)^{2}+20 x=11 \) (vi) \( 4 a^{2} x^{2}+8 a b x+4 b^{2}=0 \)
(vii) \( 1=\frac{13 x}{12 x^{2}+3} \quad \) (viii) \( (3 x+1)^{2}+(x-2)^{2}=50 \)
