Example

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

Question

$$\left. \begin{array} { l } { \quad 7 x ^ { 2 } y + 21 x - 14 x y = } \end{array} \right.$$

Answer

$$7*As*e^3*tAc*IM*s*g*n^2*m^2*o*p*l^2*t*y^2*x^2+21*x-14*x*y$$

Solution


Use Product Rule: \({x}^{a}{x}^{b}={x}^{a+b}\).
\[Ass\imath g{n}^{2}{m}^{2}{e}^{3}tAcop{l}^{2}t{y}^{2}\times 7{x}^{2}+21x-14xy\]
Regroup terms.
\[7As{e}^{3}tAc\imath sg{n}^{2}{m}^{2}op{l}^{2}t{y}^{2}{x}^{2}+21x-14xy\]
