Respuesta :
find a common factor 4 is divisible by each of the numbers. as for the variables get the lowest exponent from the whole question.
ANSWER: 4ab2(7a2b2+5a-4b)
ANSWER: 4ab2(7a2b2+5a-4b)
Answer:
[tex]4ab^2(7a^2b^2+5a-4b)[/tex]
Step-by-step explanation:
28a3b4 + 20a2b2 − 16ab3.
[tex]28a^3b^4 + 20a^2b^2 - 16ab^3[/tex]
To find GCF we look at a factor that divides 28, 20 and -16
All are divisible by 4. GCF of numbers is 4
for a^3, a^2 and a. GCF is always the variable with lowest exponent that is 'a'
for b^4, b^2 and b^3 the GCF is b^2
for whole expression the GCF is 4ab^2
Now we divide each term by GCF and put 4ab^2 outside
[tex]4ab^2(7a^2b^2+5a-4b)[/tex]
