Question 276231
Please help me sove (a+2)(a-19) with the FOIL method. 
I have tried to work it out and have gotten this far:
(a+2)(a-19) = (a)(a)+ (2)(-19)+ (2)(a)+ (2)(-19)
= a squared -38 + 2a - 38
You left out the (a)(-19), made a 2nd (2)(19)
-------------------
(a+2)(a-19) = (a)(a)+ (2)(-19)+ (2)(a)+ (a)(-19)
= {{{a^2 - 17a - 38}}}
