Asap show work if possible
use quadratic formula
2w^2-28w=-98

2n^2-6n=8

-3p+17p=20

2j^2-3j=-1

Quadratic Formula = -b +- √b²- √4ac all over 2a

2w² - 28w = -98
+98 +98
2w² - 28w + 98 = 0

The equation has to be set to ax² + bx + c = 0 in order to use the quadratic formula.
= - (-28) +- √(-28)² - √4(2)(98) ÷ 2(2)
= 28 +- √784 - √784 ÷ 4
= 28 +- 0 ÷ 4
= 28 ÷ 4
= 7

There is only one solution because the discriminant is 0.

Answer for 2: his profit would be $2.88 explanation: you have to first multiply 72 and 0.12 together to get $8.64 once you do that you know how much money the shopkeeper made from selling the candy bars individually. so you have to do 8.64-5.76=2.88 hope that ; )answer for 3: yeah i’m sorry i have no idea what number 3 is. i’m sorry i couldn’t with that.
