Question

Find the product of (2p+3)(2p-3)(2p+5)

Answer 1

Answer:

Step-by-step explanation:

(2p+3)(2p-3)(2p+5)

We know that a^2 - b^2 = (a+b)(a-b)

Here a=2p and b= 3

( (2p)^2 - (3)^2 ) (2p+5)

(4p^2 - 9)(2p+5)

4p^2(2p+5) - 9(2p+5)

Ans. 8p^3 + 20p^2 - 18p - 45

Answer 2

Answer:

(2p+3)(2p-3))2p+5)

We know that a^2 - b^2 = (atb)(a-b)

Here a-2p and b=3

((2p 2-(3 2 ) (2p+5)

(4p 2-9)(2p+5)

4p 2(2p+5) - 9(2p+5)

Ans. 8p^3 +20p2 18p - 45
