Question

)If α and β are the zeros of the polynomial p(x) = x^2 – 5x+ 6, then find the
value of α + β - 3α β .

Answer 1

Answer:

-13

Step-by-step explanation:

idk if the answer is correct

Answer 2

Answer:

-13

Step-by-step explanation:

Given that,

p(x)=x^2-5x+6

Let,p(x)=x^2-3x-2x+6=0      (Since, splitting of '-5x' )

     0=x(x-3)-2(x-3)

     0=(x-3)(x-2)

case-1                                case-2

         x-3=0                                 x-2=0                        

          => x=3                              =>x=2

let,   α=3, β=2

now, given to find α+β-3αβ=3+2-3(3)(2)

=>5-18

=>-13

therefore,

α+β-3αβ=-13
