Question

Find the absolute sum of roots of the equation $$\displaystyle x^{2}+3x-4=0 $$


Solution

$$\displaystyle x^{2}+3x-4=0\Rightarrow x^{2}-x+4x-4=0$$
$$\displaystyle \Rightarrow x\left ( x-1 \right )+4\left ( x-1 \right )=0\Rightarrow \left ( x+4 \right )\left ( x-1 \right )=0$$
$$\displaystyle \therefore x=-4$$ or x = 1

Absolute Sum of roots$$|-4+1| = 3$$
