Question

Find other zeros of the polynomial 2x4-9x3+5x2+3x???? if two zerpes ate 2and 3

Answer 1

this is the required answer.

Answer 2

ŤĤĔ ĂŃŚŴĔŔ ĨŚ ĂŚ ŦŐĹĹŐŴŚ ...

X = 2+ v3 and X = 2 - v3 are Zeros of p(x)

(x-2-V3) (x-2+ v3)

(using identity (a -b) (a+b) = a2 - b2

then,

(x - 2)^2 - (V3)^2

x^2 + 4 - 4x - 3

x^2 +1-4x ...... (i)

When we divide p(x) by(i) we get the other zeros

Other zeros are :-x = 1 and x = -1/2
