Question

utilizando os casos de fatoração, fatore completamente cada polinômio f)10x^3+15x^2+40x+60 g)13x^4 y^2-13a^4 b^2 h)11ac^2+11bc^2-11ad^2-11bd^2

Answer 1

f)10x^3+15x^2+40x+60 => 10x^3+15x^2+40x+60 

5x^2(2x+3) + 20(2x+3) ==> ( 5x^2 + 20)(2x+3) 
====================================
g)13x^4 y^2-13a^4 b^2 ==> 13(x^4 y^2-a^4 b^2 )

13(x^2 y + a^2 b )(x^2 y - a^2 b )
===============================================
h)11ac^2+11bc^2-11ad^2-11bd^2 ==> 11c^2(a+bc) -11d^2(a - b)
( 11c^2 - 11d^2)(a + b)
