Question

Find the square root of (x-1) (x-2)(x2 - 3x + 2).​

Answer 1

Answer:

(x-1)(x-2)

Step-by-step explanation:

let z=(x-1) (x-2)(x2 - 3x + 2).​

=(x-1) (x-2)(x2 - 2x-x + 2).​

=(x-1) (x-2){ x(x - 2)-(x - 2).}

=(x-1)(x-2)(x-2)(x-1)

z=(x-1)²(x-2)²

now square root of z

√z=√(x-1)²(x-2)²

=(x-1)(x-2)
