Hi,
I suggest next time could you please write the expressions properly in Word format so
that the mathematical notation is understood properly. I hope this helps. If you have any
queries, don’t hesitate to ask.
Based on the above information, I assume that we can rewrite:
Express the polynomial:
x 2  xy 2 x  6 y  x  y 2 x  6 y 

Factor the polynomial:
To express the polynomial, find the roots of the equation so that ax2 + bx + c = 0
