★ CUBIC RESOLUTION ★
To make the cubic equation easier , we can eliminate the constant terms from the leading coefficients and variable respectively , which will result in the expression :
x³ + x² + x + c = 0
Now , try your best to vanish coefficient along with x²
Equation will reduce to
x³ + x + c = 0
From which we can easily solve the cubic equation by using Cardan's solution
