por favor me ayudan estos ejercicios importante
Explicación paso a paso:
[tex]\left(a-z\right)^2\\=a^2-2az+z^2[/tex]
[tex]a^4n-225b^4\\a^4n-225b^4=0\\a^4n-225b^4-a^4n=0-a^4n\\-225b^4=-a^4n\\\frac{-225b^4}{-225}=\frac{-a^4n}{-225}\\b^4=\frac{a^4n}{225}\\[/tex]
[tex]c^2-9c+8\\=\left(c^2-c\right)+\left(-8c+8\right)\\=c\left(c-1\right)-8\left(c-1\right)\\=\left(c-1\right)\left(c-8\right)[/tex]
