Question

Ayuda porfavor lo necesito para hoy :(​

Answer 1

(a + b) c - d

=c ( a + b ) - d

= ac + bc - d

(a + b)(b - a)

= a² - b²

(b - m)(c - n) + 4a²

=bc + b(-n) - mc - m(-n) + 4a²

= bc - nb - mc + mn + 4a²

(2m + 3n)(4p + b²)

=2m * 4p + 2mb² + 3n * 4p + 3nb²

= 8mp + 2mb² + 12np + 3nb²

(4m + 8p)(a² + b²)(6n - d)

=(4ma² + 4mb² + 8pa² + 8pb²)(6n - 2)

4ma² * 6n + 4ma² ( -d ) + 4mb² * 6n + 4mb² (-d) + 8pa² (-d) + 8pa² (-d) + 8pb² * 6n + 8pb²(-d)

= 24ma²n - 4ma²d + 24mnb² - 4mdb² + 48pa²n - 8pa²d + 48npb² - 8dpb²

Te ayude en 5,espero te sirva,suerte!
