factor out what the two terms have in common, then combine like terms.

2) -4[5(2x+3y)-4(x+2y)]

distribute the terms inside the [brackets], combine like terms, then factor out any common factor(s) you may see.

For first one take (p+q) common and regroup :
(p+q)(......) proceed ..

For second one you must multiply the terms :
-4(10x+15y - 4x -8y)
....proceed....
