Answer 1

Step-by-step explanation:

$\tt\red{ QUESTION}$$\tt\blue{::}$

if 2 alpha are zeroes of x square - 3x + 2 , then the value of alpha is

$\tt\red{ ANSWER}$$\tt\blue{::}$

The general form of a quadratic equation is ax² +bx +c

Whose roots are α and β

Also α + β = - b / a

αβ = c / a

On comparing 2 – 3x –x² with general form ax² +bx +c

We get a= -1 , b= -3 , c= 2

αβ = c / a

αβ = 2 / -1 = - 2
