hi can anyone help me solve these 2 problems

1)Direction: solve each polynomial equation by factoring

4x cubed + 7x squared - 5x = 6

2)Direction:Identify the roots of each equation.state the mutiplicity of each root

x to the fourth power + 2x cubed -11x squared - 12x +36=0

and can you please explain to me how you would factor it if its factorable because im having a hard time factoring when x isnt to like the second power.hope this made sense..thanks
