Question

solve: log2(x2−x−2)=2

Answer 1

\[ \log_{2}(x ^{2}-x-2)=2 \]

Answer 2

if you raise each as a power of 2

\[2^{\log_{2}(x^2 - x -2)} = 2^2\]

you end up with

x^2 - x - 2 = 4

since \[a^{\log_{a}(u)} = u\]

now you should be able to solve the equation

Answer 3

x = 3, -2

Answer 4

thank you guys :)
