X+3+42+-63x2

ANSWER
=-63x2+43x+3

Answer 1

math is good

notation, not so much.
Online, use ^ to indicate exponents.
x^2, not just x2

also, the line (-9x/ x ... is confusing.
Where did the division come from?

Answer 2

Online "^" is used to indicate an exponent, e.g., x^2 = x squared.
3 + 43x - 63x^2
