i have a few questions on an assignment, due to rushed notes which i am struggling to make head nor tail of, i am struggling to understand the method to complete them.

6t^7x^9 - 8x^4t^9 = 0

i know these are not too hard as a lot of students in class finished the assignment very quickly, unfortunatly i am still scratching my head. can anyone explain a method to simplify the above equation so that i can put it into action?

thanks
