Answer:

x₁ = 2 x₂ = 1

Step-by-step explanation:

We solve this equation by factoring it

x² - 3x +2 = 0

We look for two numbers that if we add them the result is -3, and also if we multiply them the result is 2

the numbers we are looking for are -2  and -1

Then we write the equation in this way

(x-2)(x-1) = 0 and finally we equal each therm to zero

x₁ - 2 = 0

x₁ = 2

x₂ -1 = 0

x₂ = 1
