Question

7. Simplify the following:
(a) (2x+p-c)2-(2x-p+ c)2
(c)(a + b + c)2+(a - b + c)2+(a+b-c)2​

Answer 1

Step-by-step explanation:

Apply the formula a 2−b2 =(a+b)(a−b) to simplify the expression.

=(2x+p−c) 2−(2x−p+c)2

=(2x+p−c+2x−p+c){2x+p−c−(2x−p+c)}

=(4x)(2x+p−c−2x+p−c)

=(4x)(2p−2c)

=8x(p−c)

=8xp−8xc
