2. The polynomial 3x3 – 2x2 – 12x + 8 is denoted by f(x). (a) Use factor theorem to show that (x + 2) is a factor of f(x).

Step-by-step explanation:

according to the question

x+2=0

x=-2

therefore

we have proven that x+2 is a factor of 3x³-2x²-12x+8

let's factorise 3x³-2x²-12x+8

and

we are done

the homeowners insurance cost for a 115,000 wood frame house is 80,500.
