Question

Can anyone help with factoring polynomials?

Answer 1

Factor completely: 5ab(x + 6) − 4(x + 6)
Select one:
a. Prime
b. (x + 6)(5ab + 4)
c. (x + 6)(ab)
d. (x + 6)(5ab − 4)

Answer 2

what do you think?

Answer 3

im not sure

Answer 4

where to start

Answer 5

do you know how to expand this
(a+b)(c+d)

Answer 6

ac + ad + bc + bd
?

Answer 7

yes!!

Answer 8

is this how you did it?
(a+b)(c+d)
=a(c+d)+b(c+d)
=ac+ad+bc+bd

Answer 9

yes :)

Answer 10

now look closely at the second step
a(c+d)+b(c+d)

Answer 11

ac + ad + bc + bd?

Answer 12

no...i asked you to expand.
your question is asking you to go in reverse (factorize)

the question resembles a(c+d)+b(c+d)
go reverse to get back (a+b)(c+d)

Answer 13

Walk me through this please... confused :/

Answer 14

(m+n)(p+q)
=m(p+q)+n(p+q)

Answer 15

you get what i just did there?

Answer 16

not really...

Answer 17

how did you expand (a+b)(c+d) ?

Answer 18

Multiplid everything

Answer 19

do you know "distributive property of multiplication over addition"?
