Question

Hola soy nuevo esta tarea es para hoy el que me ayuda le doy corona y lo sigo

Answer 1

Respuesta:

5m*(2m^2-7m) = 10m^3 - 35m^2

-6p*(p-3)=-6p^2 +18p

-4x*(-x+8x^3)= 4x^2 - 32x^4

(48m^3p^4-72mp):(-12mp) = -4m^2p^3 + 18

(m-3)(6m-2) = 6m^2-2m-18m + 6 = 6m^2 -20m +6

(x^2 + 4m) (-3+m) = -3x^2 + mx^2 -12m + 4m^2

(p-5p^2)(-1+p) = -p+p^2+5p^2-5p^3 = -5p^3 6p^2-p

(n-6)(-n-2) = -n^2-2n+6n+12 = -n^2+4n+12

Answer 2

Aplica la propiedad distributiva.

a. 5m.(2m²-7m) = 5m × 2m² - 5m × 7m =10m³ - 35m²

b. (-6p) (p-3) = (-6p) × (p) - (-6p) × (3) = -6p² + 18p

c. (4x).(-x+ 8x³)= (4x) × (-x) + (4x) × (8x³) = -4x² + 32x⁴

d. (48m³p⁴ - 72mp): (-12mp) = -4m²p³ + 6

Aplica la propiedad distributiva y después opera con los términos que sean semejantes.

a. (m-3) (6m-2) = (m)(6m) + (m)(-2) + (-3)(6m) + (-3)(-2)  = 6m²-2m-18m+6  

b. (x²+ 4m) (-3+m) = (x²)(-3)+(x²)(m) + (4m)(-3) + (4m)(m)  = -3x²+x²m-12m+4m²  

c. (p-5p²).(-1+p)= (p)(-1) + (p)(p) + (-5p²)(-1) + (-5p²)(p)  = -p+p²+5p²-5p³  

d. (n-6).(-n-2)=(n)(-n) + (n)(-2) + (-6)(-n) + (-6)(-2)  = -n²-2n+6n+12
