Complete the table to find the product of [tex]\left(5y^2 - 6y\right)\left(7y^7 - y^3\right)[/tex].

Provide your answer in descending order of exponents.



Answer :

To find the product of [tex]\(\left(5 y^2-6 y\right)\left(7 y^7-y^3\right)\)[/tex], we will use the distributive property (also known as the FOIL method for binomials). We can break it down into steps:

1. First Term from the First Expression, Multiplied by Each Term in the Second Expression:
[tex]\[ (5y^2) \cdot (7y^7) = 35y^9 \][/tex]
[tex]\[ (5y^2) \cdot (-y^3) = -5y^5 \][/tex]

2. Second Term from the First Expression, Multiplied by Each Term in the Second Expression:
[tex]\[ (-6y) \cdot (7y^7) = -42y^8 \][/tex]
[tex]\[ (-6y) \cdot (-y^3) = 6y^4 \][/tex]

3. Combining All These Products:
[tex]\[ 35y^9 - 5y^5 - 42y^8 + 6y^4 \][/tex]

4. Writing in Descending Order of Exponents:
[tex]\[ 35y^9 - 42y^8 - 5y^5 + 6y^4 \][/tex]

Therefore, the product of [tex]\(\left(5 y^2-6 y\right)\left(7 y^7-y^3\right)\)[/tex] in descending order of exponents is:

[tex]\[ 35y^9 - 42y^8 - 5y^5 + 6y^4 \][/tex]
