a⋅(b-2)=3b
3(r+2s)=2t-4
a⋅(b-2)=3b

Question

$$\left. \begin{array} { l } { \quad 3.1.1 \quad 10 x ^ { 2 } + 12 x - 17 x - 9 x ^ { 2 } } \end{array} \right.$$

Answer

$$-3*JESTION*Si*e*m*p*l^3*f^2*y*t*h*o^2*w*n*g$$

Solution


Regroup terms.
\[3mplllffythoowngJESTIONSi\imath e\imath \]
Simplify.
\[3mp{l}^{3}{f}^{2}yth{o}^{2}wngJESTIONSi\imath e\imath \]
Use Product Rule: \({x}^{a}{x}^{b}={x}^{a+b}\).
\[3mp{l}^{3}{f}^{2}yth{o}^{2}wngJESTIONSi{\imath }^{2}e\]
Use Square Rule: \({i}^{2}=-1\).
\[3mp{l}^{3}{f}^{2}yth{o}^{2}wngJESTIONSi\times -1\times e\]
Simplify.
\[-3mp{l}^{3}{f}^{2}yth{o}^{2}wngJESTIONSie\]
Regroup terms.
\[-3JESTIONSiemp{l}^{3}{f}^{2}yth{o}^{2}wng\]
