Answer:

[tex]=5x^{2} +2x-4-(2x^{2} +6x-6)\\=5x^{2} +2x-4-2x^{2} -6x+6\\=5x^{2} -2x^{2} +2x-6x-4+6\\=3x^{2} -4x+2[/tex]

Step-by-step explanation:

Hence,5x²+2x-4 and 2x²+6x-6 are the two polynomials.

To create them:

Let,5x²+2x-4 be the first polynomial and x be the another

Now, we have,

→5x²+2x-4-x=3x²-4x+2

→5x²+2x-4-(3x²-4x+2)=x

→5x²+2x-4-3x²+4x-2=x

→x=3x²-4x+2
