Hello can you me find all the products

Rewrite the following quadratic functions in intercept or factored form. show your work. y = 4x^2 - 19x- 5

In dire need~! describe how to use area models to find the quotient 2/3 divided by 1/5. check your work by also finding the quotient 2/3 divided by 1/5 using numerical operations only.
