Consider the following simplified algebraic expression. 10x+y+6x2 - 7y2-6
Which could be the original expression?
8x²y+7x? - 5y2+3x-2+2x²y-x?- 2y?+3x-4
8x²y+7x2 - 5y2 +3x-2+2x+y- x - 2y2-3x-4
O 8x?yyy7x2 – 5y2 +3x+2+2x+y= x2 - 2y2 - 3x-4
O Bxy+7x2 - 5y2 + 3x-2-2xºy- x2 - 2y2-3x-4
Please help

the first question mark is 6 and the second question mark is 26 (the square root)
