Question

factorize
x-1-(x-1)+9x-9​

Answer 1

Answer:

x=-1 or x=8

Step-by-step explanation:

[x-1][x-1]+9x-9

[x^2+1-2x]+9x-9

x^2-7x-8

x^2+1x-8x-8

x[x+1]-8[x+1]

[x+1][x-8]

x=-1 or x=8

Answer 2

$Given \: x - 1 - (x-1) + 9x - 9$

$= 1(x - 1) - 1(x-1) + 9(x - 1)$

$= ( 1-1+9)(x-1)$

$= 9(x-1)$

Therefore.,

$\red{ x - 1 - (x-1) + 9x - 9 }\green {= 9(x-1)}$
