Needed help for this equation.

Question

(6 - 5x)(6 + 5x)=?

Answer 1

(6-5x)(6+5x)= 

 

you need to visualize the foil method, Krill.

 

first start with the 6 in the first set and multiple with the second set <whole>

6 (6+5x) = 36+30x

 

second start with the -5x in the first set and multiple with the second set <whole>

-5x (6+5x) = -30x-25x^2

 

note

x^2 = x to the 2nd power  

 

after the basic foil is done, you must combine all like terms. 

x^2 terms may not be combine with 2x terms in short.

 

36-25x^2 should be your answer.

Answer 2

This is in the form (a-b)*(a+b). See my answer to your previous question to figure the answer to this one.
