Compute the convolution y(n) = x(n) * h(n) , Where x(n) = {1,1,0,1,1} and h(n) = {1,-2,-3,4} , Using : Graphical Method

Let P(x) = (x - 1)(x - 2)²(x-3)³. Find the set of such that X (a) P(x) = 0, (b) P(x) 0.

Expand (y-3x)*. A y + 12yx + 54y*x² +108y²x³ +81x* B. y +4y°x + 6y*x² + 4y²x³ + x* y - 12y x + 54y*x² – 108 y²x³ + 81 x* y* – 12y³x + 54 y²x² – 108 yx³ +81 x* - y + 4y'x +6y°x² + 4y%x³ + y*x* Not possible to expand. OAA OB.B C.C CEE OF F E.
