Asap! answer should be in polynomial in standard form

-2 - 5y² + 42

Step-by-step 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 + 7y² - 12y² + 42 ← collect like terms

= - 2 - 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. ]

tube or goog would be a great resource to with that question

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5
