What should be added to (-5 a2b - 9 ab) to get a2b + 3 ab?

Doss [256]

Based on given conditions,

$a²b + 3 ab - (-5 a²b - 9 ab)$

$→a²b + 3 ab + 5 a²b + 9 ab$

$→(a²b + 5 a²b) + (3ab + 9 ab$

Now collecting the coefficients and adding them,

$(1 + 5)a²b + (3 + 9)ab$

$→6 {a}^{2}b + 12ab$

Hence, the 6a²b + 12ab should be added.

We have the following:

$\begin{gathered} x=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a} \\ a=5 \\ b=0 \\ c=-80 \end{gathered}$

replacing:

$\begin{gathered} x=\frac{-0\pm\sqrt[]{0^2-4\cdot5\cdot-80}}{2\cdot5}=\frac{\pm\sqrt[]{1600}}{10}=\frac{\pm40}{10}=\pm4 \\ x_1=4 \\ x_2=-4 \end{gathered}$
