2x^2 + x + 3=0 has only complex roots.
The determinant is 1-4*2*3 = -23
-23 (or any determinant) is the part under the square root sign, If that determinant is negative, knowing you cannot take the square root of a negative number, we know the answers must be complex.
Answer:
Ham costs: $8.249 repeating
Overall cost: 1.26 repeating
Step-by-step explanation:
$4.95 x 5/3= 8.249
2/3 + 3/5= (2 x 5) + (3 x 3)/ 3 x 5=
19/ 15 or 1 4/15
15 divided by 19= 1.26 repeating
