Question

( =frac{-left(3^{3} v^{2}+r^{2} alpha^{2}+x^{2} p^{2}right)}{alpha beta v} )
( left.frac{-left{(3 x+x alpha+alpha beta)^{2}-2 alpha(beta gamma(alpha+beta+gamma)}right.}{alpha beta V^{prime}}right) )
( =frac{-left{0-2.7 cdotleft(-frac{1}{2}right)right}}{7}=-1 )

# 2y + 1. B-5.a Ifa, B and y are roots of 2x + x2 - 7 = 0, then find the value of By B-6. Find the roots of 4x® + 20x2 – 23x + 6 = 0 if two of its roots are equal.
