Question

Please help asap! answer should be in polynomial in standard form

Answer 1

-2
`y^(4)` - 5y² + 42

Explanation:

Each term in the second factor is multiplied by each term in the first factor, that is

y²(- 2y² + 7) + 6(- 2y² + 7) ← distribute both parenthesis

= - 2
`y^(4)` + 7y² - 12y² + 42 ← collect like terms

= - 2
`y^(4)` - 5y² + 42 ← in standard form

[ standard form means the first term has the largest exponent of the variable, followed by other terms in descending powers of the variable. ]
