Answer 2

$\large{\boxed{\sf{\frac{1}{α}+\frac{1}{β}- αβ}}}$

$\large{\boxed{\sf{\frac{α+β}{αβ}- αβ}}}$

$\large{\boxed{\sf{\frac{-b/a}{c/a}- (c/a)}}}$

$\large{\boxed{\sf{\frac{-b}{c}-(c/a)}}}$

$\large{\boxed{\sf{\frac{-(-1)}{(-4)}-(-4/1)}}}$

$\large{\boxed{\sf{\frac{-1}{4}+4}}}$

$\large{\boxed{\sf{\frac{15}{4}}}}$
