Answer 1

Answer:

x = 1

Step-by-step explanation:

AS THIS IS A BI-QUADRATIC EQUATION THEREFORE WE HAVE TO APPLY HIT-N-TRIAL METHOD

LET X = 1

THEREFORE, X⁴+X³-7x²-X + 6

1⁴ + 1³ - 7 ( 1 )² - 1 +6

1+1-7-1+6

-5-1+6

-6+6

0

According to factor theorem if we put the value of x and the result of equation becomes zero the it is the zero of polynomial.
