Question

ln this question using factory method we have to divide the polynomials by polynomials​

Answer 1

Answer:

(x+1)(x-1)

Step-by-step explanation:

z=x^4+3x²-10

=x^4+5x²-x²-10

=x²(x²+5)-(x²+5)

x^4+3x²-10=(x²+5)(x²-1)

Dividing both sides by x²+5

(x^4+3x²-10)/(x²+5)=(x²+5)(x²-1)/(x²+5)

=(x²-1

=(x+1)(x-1)
