Question

If a and ß are the roots of equation x2 - 5x + 6
= 0, then find the value of a - B.​

Answer 1

Answer:

±1

Step-by-step explanation:

Here,

$\alpha + \beta = 5$

$\alpha \beta = 6$

$( \alpha - \beta )^{2}=( \alpha + \beta )^{2} - 4 \alpha \beta$

So,

$(\alpha-\beta )^{2} = 25-24=1 \\ \alpha - \beta = +1 \: or \: -1$
