roots are 2,-3,5

sum of zeroes = 4

product of zeroes=-30

product of sum of zeroes=[2*-3]+[-3*5]+[2*5]

=-6+[-15]+10

= 11

ans [a] is correct

equation is x^3+

niki98: okk

jackrose: Hmm

niki98: 2 ques solve the equation cosecx = 1+cotx

niki98: solve it quickly

jackrose: Wait

jackrose: 1/sinx = 1+ cosx/sinx... Taking sinx as lcm we get 1= sinx+cosx.... So dividing both sides by 1/√2 we get 1/√2cosx+1/√2sinx = 1/√2....... Then we can write cosπ/4cosx + sinπ/4sinx = 1/√2...... Cos(x-π/4) = cosπ/4.... Now comparing we get (x-π/4) = π/4 now x = π/4 + π/4 =π/2 ans

niki98: thnks
