Answer:
[tex]x^2 +10x + 1[/tex]
Step-by-step explanation:
FOIL stands for "First, Outer, Inner, Last"
It is the sum of:
· multiplying the First terms,
· multiplying the Outer terms,
· multiplying the Inner terms, and
· multiplying the Last terms
Example = (a+b)(c+d) = ac + ad + bc + bd
Applying Foil Method we get
(x + 9) (x + 1) =[tex]x^2 + x + 9x + 1[/tex]
Now on combining the like terms
(x + 9) (x + 1) = [tex]x^2 +10x + 1[/tex]
