step-by-step explanation:

35x4=140

140/20=7

The solutions of the polynomial are ,

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 , 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 by i

∴

∴

- Divide up and down by 4 to simplify the fraction

∴ ,

The solutions of the polynomial are ,
