Answer 2

$\huge\bf\red{Question}$

$\implies3x^{2}-x-4$

$\huge\bf\purple{Answer}$

$\implies3x^{2}-x-4 \\\implies 3x^{2}-(4-3)x-4 \\ \implies 3x^{2}-4x+3x-4 \\ \implies x(3x-4)+1(3x-4) \\ \implies(x+1),(3x-4) \\ \implies x+1=0,3x-4=0 \\\implies x = -1,x=-4/3$

★the root of given equation are x= -1 , x= -4/3
