Question

if x^2+4x-5 is a factor of x^4-ax^2+b find a and b​

Answer 1

Answer:a=26

b=25

Step-by-step explanation:

Since x square + 4 x minus 5 is a factor of p(x). p(x) should also be completely divisible by the factors of x square + 4 x minus 5 .By using remainder theorem we will get two equations and by solving the two equations we will be able to solve the question. I hope you understand.
