Answer 1

Answer:

Step-by-step explanation:

Using this model, we find the product equals 900 + 210 + 30+ 7 = 1147. ... Use your figure to explain the identity for a perfect square trinomial: (x + y)= x² + 2xy + y2 -----. X X². Ixy. = x2 + 2xy + y² . + 2xy +. Pepe y lxy. Luz. 7. This identity gives a rule for ... So the identity for a binomial cubed is (x + y)' = X 3+3x²y +3 xy ty. 1.
