por favor ayuda rápido​

Answer 1

Respuesta:

1. x² + 8x + 16

4. p² + 10pq + 25q²

7. 25x² + 30xy + 9y²

10. 36² - 60xy + 25y²

1. (x + 4)²= (x + 4) (x + 4=

(x) (x) = x²

(x) (4)= 4x

(4) (x)= 4x

(4) (4)= 16

R: x²+ 8x + 16

4. (p + 5q)²= (p + 5q) (p + 5q)=

(p) (p) = p²

(p) (5q)= 5pq

(5q) (p)= 5pq

(5p) (5p)= 25p²

R: p² + 10pq + 25q²

7.(5x + 3y)²= (5x + 3y) (5x + 3y)

(5x) (5x)= 25x²

(5x) ( 3y)= 15xy

(3y) (5x)= 15xy

(3y) (3y)= 9x²

R: 25x² + 30xy + 9xy²

10. (6x - 5y)²= (6x - 5y) (6x - 5y)=

(6x) (6x) = 36x²

(6x) (-5y)= -30xy

(-5y) (6x)= -30xy

(-5y) (-5y)= 25y²

R: 36x²- 60xy + 25y²
