In each of these question two equations I & II with variables a & b are given You have to solve both the equations to find the values of a & b
Mark answer if
a) a
$2a^{2}+a-1=0$
We get the factor as:
a=-1, a=0.5
$12b^{2}-17b+6=0$
Solving, we get the factor as,
b= 1.5, b= .75
Hence, b>a
Option A is correct option.
$2a^{2}+a-1=0$
We get the factor as:
a=-1, a=0.5
$12b^{2}-17b+6=0$
Solving, we get the factor as,
b= 1.5, b= .75
Hence, b>a
Option A is correct option.
