Question

If x² – 3x + 2 = 0, then the roots are

Answer 1

x² - 3x + 2 = 0

x² - 1x - 2x + 2 = 0

x( x - 1 ) - 2(x - 1) = 0

(x - 1)(x - 2) = 0

x = 1 or 2

Hope it helps you

Answer 2

Answer:

1 or 2

Step-by-step explanation:

${x}^{2} - 3x + 2 = 0 \\ {x}^{2} - 2x - x + 2 = 0 \\ x(x - 2) - 1(x - 2) = 0 \\ (x - 2) (x - 1) = 0 \\ x = 2 \\ x = 1$
