Given: (a)
2(x+3)=2x+6 and (b)
4(y-3)=4y-12.

To find: The expanded form of the given expressions.

(c)
4(m+n)=4m+4n (using
a(b+c)=ab+ac)

(d)
3(5-q)=15-3q (using
a(b-c)=ab-ac)

(e)
5(2c+1)=10c+5 (using
a(b+c)=ab+ac)

(f)
3(2x-5)=6x-15 (using
a(b-c)=ab-ac)

(g)
7(4b-1)=28b-7 (using
a(b-c)=ab-ac)

(h)
3(2x+y-5)=3((2x+y)-5)


3(2x+y-5)=3(2x+y)-15 (using
a(b-c)=ab-ac)


3(2x+y-5)=6x+3y-15 (using
a(b+c)=ab+ac)

(i)
2(6a-4b+3)=2((6a-4b)+3)


2(6a-4b+3)=2(6a-4b)+6 (using
a(b+c)=ab+ac)


2(6a-4b+3)=12a-8b+6 (using
a(b-c)=ab-ac)

(j)
6(m+n+p)=6((m+n)+p)


6(m+n+p)=6(m+n)+6p (using
a(b+c)=ab+ac)


6(m+n+p)=6m+6n+6p (using
a(b+c)=ab+ac)

(k)
y(y+2)=y^2+2y (using
a(b+c)=ab+ac)

(l)
g(g-3)=g^2-3g (using
a(b-c)=ab-ac)

(m)
n(4-n)=4n-n^2 (using
a(b-c)=ab-ac)

(n)
a(b+c)=ab+ac (using
a(b+c)=ab+ac)

(o)
s(3s-4)=3s^2-4s (using
a(b-c)=ab-ac)

(p)
2x(x+5)=2x^2+10x (using
a(b+c)=ab+ac)

(q)
4y(x-3)=4xy-12y (using
a(b-c)=ab-ac)

(r)
5a(2b-5)=10ab-25a (using
a(b-c)=ab-ac)

(s)
4a(3b+2c)=12ab+8ac (using
a(b+c)=ab+ac)

(t)
5p(4p-5q)=20p^2-25pq (using
a(b-c)=ab-ac)
