Find the product of (x + 5)^2.
x2 − 10x + 25
x2 − 25
x2 + 25
x2 + 10x + 25

Answer 1

1) [B]: " x² − 10x + 25 " .
_____________________________________________________
2) [D]: " x² + 10x + 25 " .
_____________________________________________________
Note:
_____________________________________________________
1) (x − 5)² = (x − 5) (x − 5) = x² − 5x − 5x + 25 = x² − 10x + 25 .

2) (x + 5)² = (x + 5) (x + 5) = x² + 5x + 5x + 25 = x² + 10x + 25 .
