Example

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

Question

$$\left. \begin{array} { l } { ^ { 2 } - 12 a b } \\ { 49 a ^ { 2 } - 12 c ^ { 2 } } \end{array} \right.$$

Answer

$$-12*a*b+18*eCo*e*IM*t^2*h*n^2*c*p*a^2*r*b^2$$

Solution


Use Product Rule: \({x}^{a}{x}^{b}={x}^{a+b}\).
\[{t}^{2}heCo{n}^{2}ecp{a}^{2}\imath r\times 18{b}^{2}-12ab\]
Regroup terms.
\[18eCoe\imath {t}^{2}h{n}^{2}cp{a}^{2}r{b}^{2}-12ab\]
Regroup terms.
\[-12ab+18eCoe\imath {t}^{2}h{n}^{2}cp{a}^{2}r{b}^{2}\]
