Step-by-step explanation:

so basically to solve quadratic equations

some formulas are used

so one of them is alpha cube +beta cube

$= ( \alpha + \beta )cube - 3 \alpha \beta ( \alpha + \beta )$

some more useful formulas are as follows=

$\alpha \: square + \beta \: square = \\ ( \alpha + \beta )square - 2 \alpha \beta$

$( \alpha - \beta )square = \alpha \: square + \beta \: square - 4 \alpha \beta$
