Question

if a-1 1/2 b=3 and c=1 then value of b2-4ac​

Answer 1

Step-by-step explanation:

a=11/2, b=3,c=1

b2-4ac

= 3×2-4×11/2×1

= 6-2×11×1

= 6-22

= 16

Answer 2

$\Large\bf\red{Solution:- }$

$\bf a=\dfrac{11}{2}$

$\bf b=3$

$\bf c=1$

$\bf\green {b^2-4ac}$

$\bf\implies {3^2-\cancel 4^2×\dfrac{11}{\cancel 2}×1}$

$\bf\implies {9-22}$

$\bf\implies{\underline{\boxed{\pink {-13}}}}$
