Use the FOIL method. Multiply terms in this order:
First: (5p+4)(4p+6) ---> 5p x 4p = 20p^2
Outer (5p+4)(4p+6) ---> 5p x 6 = 30p
Inner (5p+4)(4p+6) ---> 4 x 4p = 16p
Last (5p+4)(4p+6) ---> 4 x 6 = 24
Add the terms:
20p^2 + 30p + 16p + 24
Then simplify the terms:
20p^2 + 46p + 24
Follow the same steps with the other problems.
