Question

Add the following algebraic expression using both horizontal and vertical methods. Did you get the same answer with both methods.
$2 x^{2} - 6 x + 3; - 3 x^{2} - x - 4; 1 + 2 x - 3 x^{2}$

Solution

By vertical method
$\begin{matrix} 2 x^{2} - 6 x + 3 - 3 x^{2} - x - 4 - 3 x^{2} + 2 x + 1 - -------------- - - 4 x^{2} - 5 x + 0 - -------------- - \end{matrix}$
By horizontal method
$\begin{matrix} 2 x^{2} - 6 x + 3 - 3 x^{2} - x - 4 - 3 x^{2} + 2 x + 1 = - 4 x^{2} - 5 x + 0 \end{matrix}$
$1 = 2$ both answer are same
