Question

(2p+3) (2p-4) (2p-5) expand the following using the formula (x+a) (x+b) (x+c)
$(x + a)(x + b)(x + c)$
​

Answer 1

Step-by-step explanation:

(x + a)(x + b)(x + c) =

x^3 + (a + b + c)x^2 + (ab + bc + ca)x + abc

(2p + 3)(2p - 4)(2p - 5) =

(2p)^3 + (3 - 4 - 5)(2p)^2 + (-12 - 15 + 20)(2p) + (3)(-4)(-5)

8p^3 - 24p^2 - 34p + 60
