Answer:
x₁ = 2 x₂ = 1
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
