Answer:

$\large\boxed{1.\ 4x^4 - 28x^3 + 48x^2=4x^2(x-4)(x-3)}\\\boxed{5x^2 - 13x - 6=(x-3)(5x+2)}$

Step-by-step explanation:

$1.\\4x^4 - 28x^3 + 48x^2=4x^2(x^2-7x+12)=4x^2(x^2-4x-3x+12)\\\\=4x^2\bigg(x(x-4)-3(x-4)\bigg)=4x^2(x-4)(x-3)$

$2.\\5x^2 - 13x - 6 =5x^2-15x+2x-6=5x(x-3)+2(x-3)\\\\=(x-3)(5x+2)$
