factor e^{jt}+e^{-jt}

factor

e^{j t} + e^{- j t}

e^{- j t} (e^{2 j t} + 1)

Solution steps

e^{j t} + e^{- j t}

Apply exponent rule:

a^{b + c} = a^{b} a^{c}

e^{j t} = e^{- j t} e^{2 j t}

= e^{- j t} e^{2 j t} + e^{- j t}

Factor out common term

e^{- j t}

= e^{- j t} (e^{2 j t} + 1)

20 ah - 5 ak - 32 y h + 8 y k

(x + 3) 2 + 14 (x + 3) + 49

(a - b)^{3} - 27
