(x-2) is not a factor of f(x)

Step-by-step explanation:

if (x-2) is factor of f(x) then f(x)=0

f(2)= ${2^3}-2(2^2)+{2\times2+3}$

f(2)=7 $\neq{0}$ hence (x-2) is not a factor of f(x)

10x - 3 = x + 2 + 2x - 1
10x - 3 = 3x + 1
-3x on both sides
7x - 3 = 1
-1 on both sides
7x - 4

(Check 7x - 4 by adding them all up to equal 10x - 3)
x + 2 + 2x - 1 + 7x - 4 = 10x - 3
combine liked terms
10x - 3 = 10x - 3

D) 7x - 4
