Question

.EFECTUE LAS SIGUIENTES OPERACIONES DE LOS PRODUCTO NOTABLE

. (2×+4)^

. (3×+2)(3×-2)

. (4m-n)3

. (5n-4)^
​

Answer 1

Respuesta:

. (2x+4)^

$\left(2x+4\right)^2$

$=\left(2x\right)^2+2\cdot \:2x\cdot \:4+4^2$

$=4x^2+16x+16$

. (3×+2)(3×-2)

$\left(3x+2\right)\left(3x-2\right)$

$=\left(3x\right)^2-2^2$

$=9x^2-4$

.(4m-n)3

$\left(4m-n\right)^3$

$=\left(4m\right)^3-3\left(4m\right)^2n+3\cdot \:4mn^2-n^3$

$=64m^3-48m^2n+12mn^2-n^3$

. (5n-4)^

​$\left(5n-4\right)^2$

$=\left(5n\right)^2-2\cdot \:5n\cdot \:4+4^2$

$=25n^2-40n+16$
