If a and b are the roots x2−3x+p=0 and c, d are roots of x2−12x+q=0, where a, b, c, d form a G.P. Prove that (q+p):(q−p)=17:15.
If x2+px + q = 0 is the quadratic equation whose roots are a – 2 and b – 2 where a and b are the roots of x2 - 3x + 1 =0, then
If a,b are roots of equation
x²+px-q=0 and
c,d are roots of equation
x²+px+r=0
Prove that
(a-c)(a-d)=(b-c)(b-d)=q+r
