I'm currently learning for my maths exam, and in the part about boolean algebra I came across an exercise that I can't seem to solve. I probably only need the first few steps to get started.
$$ (xyz + uv)(x+\overline{y}+\overline{z}+uv) $$
Usually, if I get into trouble, I can fall back to a truth table or VK-diagram, but that's just too much work for 5 variables.
Thanks in advance!

Multiply the terms in the two brackets. You get: $$ xyz + 0 + 0 + xyzuv + xuv + \overline{y}uv + \overline{z}uv + uv$$ $$ xyz(1+uv) + uv(1+x+\overline{y}+\overline{z})$$ $$ xyz + uv $$
NOTE:
$1 + x = 1$
$1.x = x$
$x.x = x$
$x.\overline{x} = 0$
