Example

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

Question

$$5^{\circ}+6^{\circ}-7^{\circ}-9^{\circ}$$

Answer

$$-4*de*g-42*de*e*g^2*d$$

Solution


Take out the constants.
\[5deg+(6\times -7)ggddee-9deg\]
Simplify  \(6\times -7\)  to  \(-42\).
\[5deg-42ggddee-9deg\]
Use Product Rule: \({x}^{a}{x}^{b}={x}^{a+b}\).
\[5deg-42{g}^{2}ddee-9deg\]
Regroup terms.
\[5deg-42dee{g}^{2}d-9deg\]
Collect like terms.
\[(5deg-9deg)-42dee{g}^{2}d\]
Simplify.
\[-4deg-42dee{g}^{2}d\]
