In Triangle ABC ,Angle B=90 and BD perpendicular AC, if AC=9 cm and AD=3 cm then BD is equal to
1. 2√2 cm
3. 2√3 cm
form a quadratic polynomial whose zeroes are 4 and 6
If α and β are the zeros of the quadratic polynomial f(x) = x2 - px + q, prove that a2/b2 + b2/a2 = p4/q2 - 4p2/q + 2
Given thatαandβare the zeroes of the quadratic polynomialf(x) =x2–px+q
