Question

please give me answers of 4th questions ​

Answer 1

Step-by-step explanation:

f(x)=x*3-x

=x(x*2-1)

therefore, x=0,x=1 and x=-1

$\\ \alpha = 0 \: \: \: \beta = 1 \: \: \: \gamma = - 1 \\ \alpha + \beta + \gamma = 0 + 1 - 1 = 0 \\ \alpha \beta + \beta \gamma + \gamma \alpha = 0 \times 1 + 1 \times - 1 + - 1 \times 0 = - 1 \\ \alpha \beta \gamma = 0 \times1 \times - 1 = 0$

hope it helps u mark me as a brilliant
