The only thing we need to do to get this polynomial in standard form is rearrange the terms!
x+7-4x^3 -4x^3+x+7 is the polynomial written in standard form. Remember to keep track of the negatives!
The GCF of the polynomial 24x^5+18x^9 is... 6x^5 Because it is the greatest term that goes into both 24x^5 AND 18x^9! This will end up helping you factor later on. 6x^5(4+3x^4)
