    45x^2+60x+20

    I would first pull out a common factor of 5:

    5(9x^2+12x+4)

    5({\color{green}9x^2+6x}+{\color{blue}6x+4})

    Pull out a 3x from the first term, and a 2 from the second:

    5\left(3x({\color{red}3x+2})+2({\color{red}3x+2})\  right)

    5(3x+2)(3x+2)=\color{red}\boxed{5(3x+2)^2}

    Hope this makes sense!!
