2x +4)° 2x-9)°= 4x 2 +8x−9=3
Pull out like factors :
2x + 4 = 2 • (x + 2) (4 • (x + 2) • x) - 9
4x • (x + 2) - 9
Factoring 4x2+8x-9
The first term is, 4x2 its coefficient is 4 .
The middle term is, +8x its coefficient is 8 .
The last term, "the constant", is -9
Step-1 : Multiply the coefficient of the first term by the constant 4 • -9 = -36
Step-2 : Find two factors of -36 whose sum equals the coefficient of the middle term, which is 8 .
-36 + 1 = -35
-18 + 2 = -16
-12 + 3 = -9
-9 + 4 = -5
-6 + 6 = 0
-4 + 9 = 5
-3 + 12 = 9
-2 + 18 = 16
-1 + 36 = 35

Answer:
a. the order processing fee changed to $ 15 and each bottle charge changed to 115%
b. the equation of cost will be changed to : (1.2 x 1.15) b + 15 = 1.38b + 15
Step-by-step explanation:
a. the order processing fee changed to $ 15 and each bottle charge changed to 115%
b. the equation of cost will be changed to : (1.2 x 1.15) b + 15 = 1.38b + 15
* this equation limited to a single order with b bottles
