Question

Combine like terms. (5x+1)(5x-1)

Answer 1

Answer:

25x^2-1

Step-by-step explanation:

so you have to use the FOIL method which is F: First O: Outer I: Inner L: Last

So for (5X+1)(5X-1) you multiply 5x by 5x

which equals 25x^2

then you multiply 5x by -1 which is -5x

then you multiply 5x and 1 which is 5x

and you subtract 5x by -5x which is 0

finally you multiply 1 and -1 which is -1 and you put it all together which is 25x^2 -1

Answer 2

Answer:

Apply the distributive property.

5 x ( 5 x ) + 5 x⋅ − 1 + 1 ( 5 x ) + 1 ⋅ − 1 DO THIS THREE TIMES THEN THE ANWER WILL/SHOULD BE 25 x 2 − 1
