Find all the zeroes theof the polynomial x^4_3x^3+6x_4 if two of its zeroes are √2 and -√2​

Answer»

Answer:

2&1

Step-by-step explanation:

x=root2

x= - root2

then

(x-root2) × ( x+root2)

=(x^2-2)

DIVIDE x^4-3x^3+6x-4 with (x^2-2)

you will get an EQUATION:

x^2-3x+2

then solve it by spliting method:

x^2-2x-x+2

x(x-2) - 1(x-2)

( x-2)(x-1)

x-2 =0

x=2

x-1=0

x=1
