Example

3(r+2s)=2t-4
a⋅(b-2)=3b
3(r+2s)=2t-4
a⋅(b-2)=3b

Question

$$\left. \begin{array} { l } { \frac { H \cdot ( F } { 2 } - a ^ { 2 } - a + 2 , a ^ { 2 } + a ^ { 2 } - a - 1 } \\ { 2 a ^ { 2 } - a ^ { 2 } - a + 2 , a ^ { 2 } - a - 1 } \end{array} \right.$$

Answer

$$2*Fi*n*d*a^2-a^2-a+2;a^2+a^2-a-1$$

Solution


Regroup terms.
\[\begin{aligned}&2Find{a}^{2}-{a}^{2}-a+2\\&{a}^{2}+{a}^{2}-a-1\end{aligned}\]
