Find the Product. (9f+10)^(2)

Question

Find the Product.

`(9f+10)^(2)`

Answer 1

81f^2+180f+100

Explanation:

(9f+10)^2

you can group it so it's:

(9f+10)(9f+10)

and then multiply that out (FOIL)

9f*9f = 81f^2

9f*10=90f 10*9f=90f 90f+90f=180f

10*10=100

Answer 2

81f^2 + 180f + 100

Explanation:

(9f +10)(9f+10)= 81f^2+ 90f+ 90f+100 = 81f^2 + 180f +100
