Question 569032
<br>
The careless response from tutor @CoreyThePenguin is not correct, as it does not use the correct original expression.<br>
{{{16a^6b^6}}}
{{{4ab^4}}}
{{{-8ab^7}}}<br>
The coefficients 16, 4, and -8 have a GCF of 4.
The "a" factors are a^6, a, and a; their GCF is a.
The "b" factors are b^6, b^4, and b^7; their GCF is b^4.<br>
The GCF of the given terms is {{{4ab^4}}}.<br>
ANSWER: {{{16a^6b^6+4ab^4-8ab^7 = 4ab^4(4a^5b^2+1-2b^3)}}}<br>
