Answer:
a) 21a(2x+3y)(2b-1)
b)
[tex]16xy^2(1-3x)(4y+3)[/tex]
Step-by-step explanation:
Monomial has one term.
Binomial is expression with two terms.
a) (14x+21y)(6ab-3a)
For 1.st bracket common factor is 7, and for second it is 3a:
7(2x+3y)3a(2b-1)
Now, multiply 7 and 3a:
21a(2x+3y)(2b-1)
b) [tex](4x-12x^2)(16y^3+12y^2)[/tex]
For first bracket common factor is 4x and for second [tex]4y^2[/tex]:
[tex]4x(1-3x)4y^2(4y+3)[/tex]
Just need to simplify :
[tex]16xy^2(1-3x)(4y+3)[/tex]
