The value of b^2-4ac is known as the discriminant of a quadratic function, and can tell you how many roots exist of this function depending on what it is equal to.
Start by moving the -1 to the other side, as we need this function to equal zero.
2x^2 + 3x + 1 = 0
This is now the standard form ax^2 + bx + c = 0. Plug each value that corresponds into the discriminant equation.
b^2-4ac
(3)^2 - 4(2)(1)
9 - 8
1
The value of the discriminant is 1, meaning that two real roots exist for the function described.
Factor it should be
8(v-8)(v+7)
Step 1:
Recruiter fee:
15% x $178,450= $26,767.50
Step 2:
Add all costs
$26,767.50 + $178,450 + $1,341 + $713.98= $207,272.48
$207,272.48 total cost of hiring
Hope this helps! :)
