<span>i think you mean discriminant in part A
</span>
Δ=b^2-4ac=256-4*2*3=256-24=232
it is positive so it has two answers.
Part B
you can find Δ
Δ=b^2-4ac=9-4*9*(-2)=81
x1=-3+9/18=6/18=1/3
x2=-3-9/18=-12/18=-2/3
Answer:
it is 4/45

Answer:
Step-by-step explanation:
Let the gross salary be x.
<u>Then after deduction it becomes:</u>

<u>Since the amount is known, the gross salary is:</u>
- 078x = 2880
- x = 2880/0.78
- x = 3692 rounded to whole number
<u>Answer</u>: $3692
