Question

1-Determine a delta.

A)-(x+2)² x²+2 x+ 1 +1²=x 2+2 x 1
B)-(x +3)²+ 2. x +3 +3²=x² + 6 x +9
C)-(x +4)² x².+4 + 4²=x² +8 x +16
D)-(x +5)² x 2. x 5 + 5²= x² + 10 x +25
E)-(x + 6)² x 2 x 6 + 6² =x² + 12 x + 36

quero sabe a delta dessas equações... me ajudem

Answer 1

A)

(x + 2)² = x² + 2.2x + 2² = x² + 4x + 4

********************************************
B)

(x + 3)² = x² + 2.3x + 3² = x² + 6x + 9

*************************************************
C)

(x + 4)² = x² + 2.4.x + 4² = x² + 8x + 16

***********************************************
D)

(x + 5)² = x² + 2.5x + 5² = x² + 10x + 25

******************************************************

E)

(x + 6)² = x² + 2.6.x + 6² = x² + 12x + 36
