Factor the perfect-square trinomial in y = (x2 + 2x + 1) − 1− 1.

(x+1)²

Step-by-step explanation:

Here, the given expression is,

Since, a perfect-square trinomial is a trinomial that can be expressed as the square of a binomial,

Now, we can write,

Where, x+1 is a binomial,

Now, in the given expression,

The trinomial can expressed as the square of a binomial,

Thus, in the given expression,

is the perfect-square trinomial

And, its factor form is (x+1)².

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1
