Distribute (x2 + 2xy + y2)(x+1) and show

Changes made to your input should not affect the solution:

 (1): "y2"   was replaced by   "y^2".  1 more similar replacement(s).

 1.1    Factoring    x2 + 2xy + y2 

Try to factor this multi-variable trinomial using trial and error 

 Found a factorization  :  (x + y)•(x + y)

 1.2    x2  +2xy  +y2  is a perfect square 

 It factors into  (x+y)•(x+y)
which is another way of writing  (x+y)2

How to recognize a perfect square trinomial:  

 • It has three terms  

 • Two of its terms are perfect squares themselves  

 • The remaining term is twice the product of the square roots of the other two terms

step-by-step explanation:

2 tens + 6 ones

1 ten + 16 ones

0 tens + 26 ones

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)
