4 packs of water and 7 packs of candy bars

step-by-step explanation:



The solutions of the polynomial are  x=-\frac{1}{2}+\frac{3}{2}i  ,  x=-\frac{1}{2}-\frac{3}{2}i

Step-by-step explanation:

The solutions of a polynomial is the value of x when the polynomial equal to zero

The formula of quadratic polynomial is x=\frac{-b(+/-)\sqrt{b^{2}-4ac}}{2a} , where

a is the coefficient of x²b is the coefficient of xc is the numerical term

∵ The polynomial is 4x² - 4x + 10

- Equate it by zero to find its solutions

∴ 4x² - 4x + 10 = 0

∵ The coefficient of x² is 4

∴ a = 4

∵ The coefficient of x is -4

∴ b = -4

∵ The numerical term is 10

∴ c = 10

- Use the formula to find the values of x





- Substitute  \sqrt{-1}  by i



- Divide up and down by 4 to simplify the fraction

x=-\frac{1}{2}+\frac{3}{2}i   ,   x=-\frac{1}{2}-\frac{3}{2}i

The solutions of the polynomial are  x=-\frac{1}{2}+\frac{3}{2}i  ,  x=-\frac{1}{2}-\frac{3}{2}i
