Question

13. 16(2p - 3q)2 - 412p-3q)
16. (x + y)(2x + 5) - (x + y)(x+3)

please anyone help me to do this


​

Answer 1

Answer:

Answer

16(2p−3q)

2

−4(2p−3q)

=4(2p−3q)[4(2p−3q)−1] take 4(2p-3q) common,

=4(2p−3q)(8p−12q−1)

this is the first question answer second I don't know

Answer 2

Answer:

16 (2p-3q) 2 -4 (2p-3q)

= 4 (2p-3q) (4 (2p-3q) -1}

= 4 (2p-3q) (8p-12q-1)

answer

second answer

(x+y)(2x+5)−(x+y)(x+3), take (x+ y) common,

(x+y)(2x+5)−(x+y)(x+3), take (x+ y) common, =(x+y)(2x+5−x−3)

(x+y)(2x+5)−(x+y)(x+3), take (x+ y) common, =(x+y)(2x+5−x−3)=(x+y)(x+2)
