Question

what must be added to x⁴ - x³ + x² + x + 3 to obtain 5x² + 10xy - y²​

Answer 1

Answer:

Let, If we add m in x⁴-x³+x²+x+3 , we will get 5x²+10xy-y²

Now ,

x⁴+x³+x²+x+3+m= 5x²+10xy-y².

m= (5x²+10xy-y²) - ( x⁴+x³+x²+x+3)

m= 5x²+10xy-y²-x⁴-x³-x²-x-3

m= 4x²-x⁴-x³-x-3+10xy-y²

So, this is the answer.
