Solve the following please: h.(2p – q) × (3p + 2q)

i.(4x – 2y) +3 (5x + 3y)

j.2 (3a –b) (2a -4b)

k.(2a +b)2

l.(2x – 3y)2

m.(3+4) (4+2)

n.(2a –c) (3a + 4c)

o.(4x – 2y) - 3 (5x + 3y)

p.2(2x + 1)

q. x(-2x – 1)

r.-2(-x + 1)

h.

(2p-q)×(3p+5q)

(2p+3p)×(5q-q)

5p×4q

20pq.

i.

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

(4x+15x)+(5y-2y)

=19x+3y

j.

2(3a-b)(2a-4b)

(6a-2b)(2a-4b)

(6a+2a) (-4b-2b)

(8a)(-6b)

=-48ab.

k.

(2a+b)2

4a+2b.

l.

(2x-3y)2

4x-6y.

m.

(3+4)(4+2)

7*6=

42.

n.

(2a-c)(3a+4c)

(2a+3a)(4c-c)

(5a)(3c)

=15ac.

o.

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

(4x-2y)- (15x+9y)

(4x+15x )-(9y-2y)

19x-11y.

p.

2(2x+1)

4x+2.

q.

x(-2x-1)

-2x-1x

-3x.

r.

-2(-x+1)

2x-2.
