Answer 1

hey mate here is your answer

to solve this question in less time you have to use common sense

let me solve 4th equation

√2x²-3x+√2=0

so d= b²-4ac

=9-8

= 1

so the equation has real and equal roots

hence it will be matched to option (r)

so in options (IV) matched to (r) is given only in option (d) hence option d is correct

sorry for advice if it hurt you

hope it will help you
