Question

¿Cual es la solución? (4m−7p)(4m−7p) =

Answer 1

(4m-7p)(4m-7p)=(4m-7p)^2
y como (a-b)^2=a^2-2ab+b^2
(4m-7p)^2=(4m)^2-2*4m*7p+(7p)^2=16m^2-56mp+49p^2

Answer 2

Aplicando :  (a-b)² = a² - 2ab + b²

a = 4m
b = 7p

Sustituyendo:

$(4m)^2-2(4m)(7p)+(7p)^2 \\ \\ \boxed{\bf 16m^2-56mp+49p^2}\to Solucion$
