Question

Ayudas porfavor!!!

Efectúa: W = (x – 5)² - x² + 10x


Reduce: K = (a - b)(a + b)(a² + b²) + b⁴

Answer 1

Respuesta:

w=

$= {x}^{2} - 10x + 25 - {x}^{2} + 10x \\ = 25$

k=

$(a {}^{2} - b {}^{2} )( {a}^{2} + b {}^{2}) + {b}^{4} \\ = {a}^{4} - {b}^{4} + {b}^{4} \\ = {a}^{4}$

Explicación paso a paso:
