Answer:
8x • (p - c)
Step-by-step explanation:
_____________________________
Step 1 : 1.1 Evaluate : (2x+p-c)2 = 4x2+4xp-4xc+p2-2pc+c2 1.2 Evaluate : (2x-p+c)2 = 4x2-4xp+4xc+p2-2pc+c2
Step 2 :Pulling out like terms :
2.1 Pull out like factors :
8xp - 8xc = 8x • (p - c)
Final result : 8x • (p - c)

i. (a + 2)(a – 1)
= a² + (2 – 1) a + 2 × (-1)
..[∵ (x + A) (x + B) = x² + (A + B)x + AB]
= a² + a – 2
I think this is the solution for this question
