Hey, guys!

I have 2 exercises, which I don't know how to solve it without Wolframalpha.

1. Find all \(\displaystyle \mathbb{R}\) solutions of equation: \(\displaystyle 4x^4 + 4x^3 - 11x^2 - 6x + 8 = 0\).

2. Find all \(\displaystyle \mathbb{R}\) solutions of equation: \(\displaystyle x^4 - 4x^3 + 6x^2 - 4x - 3 = 0\).

I tried with formulas \(\displaystyle 4(x - A)(x - B)(x - C)(x - D)\) and \(\displaystyle (x^2 + Ax + B)(x^2 + Cx + D)\), but I couldn't figure out the solutions. Can somebody explain me how to find solutions of these 2 exercises? []
