Question

If polynomial PX is equal to x cube minus 4 x square + X + 6 then the value of zero is is

Answer 1

-1,2,3

Step-by-step explanation:

x³-4x²+x+6

zeroes of this polynomial are

-1,2,3

verification

if x = -1

(-1)³ -4(-1)²+(-1)+6=0

-1 -4 -1 +6=0

-6+6=0

0=0

if x = 2

(2)³ -4(2)² +(2) +6=0

8 -16 +2 +6=0

16 -16 =0

0=0

if x = 3

(3)³ -4(3)² +(3)+6 =0

27 -36 +3 +6 =0

36 -36 =0

0 = 0
