Question

Find the following terms (First term, second term, last term)

1 .(x + 1)'2
2. (x + 2)'2
3. (x + 3)'2
4 . (x + y)'2

Answer 1

F = FIRST TERM

S = SECOND TERM

L = LAST TERM

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
