    Trigonometric functions Factoring

    I tried to factor 1+4(\frac{1}{2}tan^2{\theta}) to be equal to  1+tan^2{\theta} but I'm having a hard time. Any tips to start me out?

    I tried to factor out 2 making it 2(\frac{1}{2}+tan^2{\theta})

    Now I'm stuck. The original equation is,

    \int{\frac{1}{1 + 4\left(\frac{1}{2}\tan{\theta}\right)^2}\left(\fra  c{1}{2}\sec^2{\theta}\right)\,d\theta}

    I need to factor the denominator so that I can apply the Trigonometric identity:
    sec^2{\theta} = 1+tan^2{\theta}

    1 + 4\left(\frac{1}{2}\tan{\theta}\right)^2 =1 + 4\left(\frac{1}{4}\tan^2{\theta}\right)
