Example

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

Question

$$\left. \begin{array} { l } { ( x - 1 ) ^ { 2 } - ( x + 4 ) ^ { 2 } ) } \end{array} \right.$$

Answer

$$-(x+4)^2+Fa*e*IM*c*t*o*r*z*(x-1)^2$$

Solution


Regroup terms.
\[Fae\imath ctorz{(x-1)}^{2}-{(x+4)}^{2}\]
Regroup terms.
\[-{(x+4)}^{2}+Fae\imath ctorz{(x-1)}^{2}\]
