Intermediate Algebra, Chapter 5, 5.2, Section 5.2, Problem 84

Solve [2p(3p6)][(5p(89p))+4p]
Multiply 1 by each term inside the parentheses.
2p(3p6)(5p+9p8+4p)


Since 5p and 9p are like terms, add 9p to 5p to get 14p.

2p(3p6)(14p8+4p)


Since 14p and 4p are like terms, add 4p to 14p to get 18p.

2p(3p6)(18p8)


Multiply 1 by each term inside the parentheses.

2p+63p(18p8)


Multiply 1 by each term inside the parentheses.

2p+63p+818p


Since 2p and 3p are like terms, add 3p to 2p to get p.

p+6+818p


Since p and 18p are like terms, subtract 18p from p to get 19p.

19p+6+8


Add 8 to 6 to get 14.

19p+14


Reorder the polynomial 19p+14 alphabetically from left to right, starting with the highest order term.

1419p
