Question

Find the values of m and n if y^2 -1 is a factor of y^4 + my^3 +2y^2 -3y +n. answer written in notebook if you give correct answer means i will mark you brainliest sure..

Answer 1

you can find answer in google

Answer 2

Answer:

hand writing is bad

Step-by-step explanation:

y⁴+my³+2y2-3y+n=0

y²=1

y=±1

put y=1

(1)⁴+m(1)³+2(1)²-3(1)+n=0

1+m+2-3+n=0

m+n=0---1

put y=-1

(-1)⁴+m(-1)³+2(-1)²-3(-1)+n=0

1-m+2+3+n=0

m=6+n

m -n=6---(2)

solve 1 and 2

2m=6

m=3

from eqn(1)

n=-3

so(m,n)=(3,-3)
