(ii) x2 - 20x +91
(iii) x² – (2+1)x + V2
(iv) a(x + 1) - x{a^2+ 1)
(v) 2V3x2 – 5x + 13 -​

Answer 1

Answer:

Determine the nature of roots of the following quadratic equations: <br> (i) `2x^(2)+5x-4=0` (ii) `9x^(2)-6x+1=0` <br> (iii) `3x^(2)+4x+2=0` (iv) `x^(2)+2sqrt2x+1=0` <br> (v) `x^(2)+x+1=0` (vi) `x^(2)+ax-4=0` <br> (vii) `3x^(2)+7x+(1)/(2)=0` <br> (viii) `3x^(2)-4sqrt3x+4=0` <br> (ix) `2sqrt3x^(2)-5x+sqrt3=0` (x) `(x-2a)(x-2b)=4ab`
