At least answer one of them!

c) x=1.23

Step-by-step explanation:

a =3

b=2

c=-7

use quadratic equation where

-2+/- square root of (2^2- (4×3×-7) ) all that over 2x3

square root of (2^2-(4×3×-7) )

= 9.38083152

2×3=6

-2+or - 9.38 all that divided by 6

-2+9.38= 7.38÷6

x=1.23

or

-2-9.38 all divided by 6

-2-9.38= -11.38 ÷6

x= -1.9

all in all x can't be negative meaning x=1.23
