simplify: (2k+7)(7k-1)\
can someone please help me solve this problem and go through the steps to solving it with me. Its too confusing for me. Thank You

  • pre algebra -

    Use FOIL (first, inner, outer, last)
    Multiply the first 2k*7k
    Then multiply the inner 7*7k
    Next, the outer 2k*-1
    Finally, the last 7*-1
    It will look like this:
    14k^2 + 49k - 2k -7
    Combine your like terms (the ks) and you are done!
    Hope this helps!
