simplify: (2k+7)(7k1)\
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

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!
