Question

X^2-5x+6 p(x) find aplha +beta-3alphabetha

Answer 1

Answer:

Step-by-step explanation:

x^2- 5x+ 6

By middle term splitting,

x^2-3x-2x+6

x (x-3)-2 (x-3)

(x-2)(x-3)

x=2,3

Here,alpha = 3 and beta = 2

So,

alpha + beta- 3alpha beta

On putting value of alpha and beta,

3+2-3×2×3

3+2-18

5-18

-13

Required ans= -13
