Question

$$\cdot(-2)^{2}+5.(-2)+6$$

Answer

$$4+^2*4+5.$$

Solution


Use Multiplication Distributive Property: \({(xy)}^{a}={x}^{a}{y}^{a}\).
\[{}^{2}{(-2)}^{2}+5.-2+6\]
Since the power of 2 is even, the result will be positive.
\[{}^{2}\times {2}^{2}+5.-2+6\]
Simplify  \({2}^{2}\)  to  \(4\).
\[{}^{2}\times 4+5.-2+6\]
Simplify  \({}^{2}\times 4+5.\)  to  \({}^{2}\times 4+5.\).
\[4+{}^{2}\times 4+5.\]
