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

it should be a and d. lmk if i'm wrong xd

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

step-by-step explanation:

a and d
