Answer 1

a) (a+4b)²=a²+8ab+16b²

b) (b-5)²=b²-10b+25

c) (3c+2)²=9c²+12c+4

d) (10-4b)²=100-80b+16b²

e) (s-3t)²=s²-6st+9t²

f) (4p+4q)²=16p²+32pq+16q²

g) (-2f-g)²=(-2f-g)(-2f-g)= 4f²+2fg+2fg+g²= 4f²+4fg+g²

h)(-5k+4m)²=(4m-5k)²=16m²-40km+25k²

i) (-7+2z)²=(2z-7)²=4z²-28z+49

j) (-5+6w)²=(6w-5)²=36w²-60w+25

k) (½z+√3)²=1/4z²+√3z+3

l) (a√2-b√5)²=2a²-2a√2*b√5+5b²
