You are watching: Factor the polynomial. 3x3 – 12x2 + 27x
Step 1 :Equation in ~ the finish of action 1 :
((3 • (x3)) - (22•3x2)) + 27x
action 2 :Equation in ~ the finish of step 2 : (3x3 - (22•3x2)) + 27x
Step 3 :
Step 4 :Pulling out like terms :4.1 pull out like factors:3x3 - 12x2 + 27x=3x•(x2 - 4x + 9)Trying to factor by dividing the center term
4.2Factoring x2 - 4x + 9 The first term is, x2 its coefficient is 1.The middle term is, -4x the coefficient is -4.The critical term, "the constant", is +9Step-1 : multiply the coefficient of the very first term by the continuous 1•9=9Step-2 : find two determinants of 9 whose sum equals the coefficient that the center term, which is -4.
Observation : No 2 such components can be found !! Conclusion : Trinomial can not it is in factored
Final result :3x • (x2 - 4x + 9)
