shubhamsrgBest ResponseYou've already chosen the best response.0
x^4  x^3 + 9x^2 2x^2  9x  18.=0 =>(x^4 + 9x^2)  (x^3 9x) (2x^2 18) =0 You see what should be the next step ?

x1 = 2 x2 = 1 x3 = 0 + 3i x4 = 0  3i
 one year ago

DeadShotBest ResponseYou've already chosen the best response.0
So, substitute (0  3i) and 1 for x^2, making it ((0  3i) + 9(1))?

DeadShotBest ResponseYou've already chosen the best response.0
so, then it would become (3i  9)

hint : divide f(x) to x^2+9 you would find your answer!

DeadShotBest ResponseYou've already chosen the best response.0
So, divide x^4  x^3 + 7x^2  9x  18 by x^2 + 9 ?
 one year ago

DeadShotBest ResponseYou've already chosen the best response.0
so it would be x^2  x + 7  x  2 ?
 one year ago

DeadShotBest ResponseYou've already chosen the best response.0
combine like terms, and it would be x^2  2x + 5 , right?
