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
