Answer:
6670/2=3335 answer:3335
Step-by-step explanation:
Answer:
F = FIRST TERM
S = SECOND TERM
L = LAST TERM
Step-by-step explanation:
1- (x+1)² = x²+2x+1
F = x²
S = 2x
L = 1
2- (x+2)² = x² + 4x + 4
F = x²
S = 4x
L = 4
3- (x+3)² = x² + 6x +9
F = x²
S= 6x
L= 9
4 (x+ y)² = x²+2xy +y²
F = x²
S = 2xy
L = y²
