Hoc can the factoring of 9x to the second power plus 18x plus 8, help factor 9a to the second power plus 18a plus 8b to the second power.

  • algebra - ,

    9x^2 + 18x + 8
    = (3x+4)(3x+2)

    in 9a^2 + 18ab + 8b^2 , (notice I corrected your middle term...)
    = (3a+4b)(3a+2b)

    the variable itself does not matter, the coefficients are the important things.
