                         (x+4)(x-12)

anonymous · Answer

= x^2 - 12x +  4x - 48
= x^2 - 8x - 48

the foil method is a memory aid but it is just as easy to remember to first multiply the second bracket by first term in first bracket then by second term in first bracket  - the distributive law for multiplication

anonymous · Answer

so its x^2-8x-48?
