What should be added to 2-3x +x² to get 3x²-4+7x?

$\huge\rm{\boxed{\blue{ Answer }}}$

2x²+10x-6

Solution :-

Let 'y' be the unknown number.

So, as per question,

=> (y) + (2-3x +x²) = (3x²-4+7x)

=> y = 3x²-4+7x -(2-3x +x²)

=> y = 3x²-4+7x -2+3x -x²

=> y = 2x²+10x-6

Hence, the value is 2x²+10x-6 .
