Given that X-Y + 1 and x 2 + 8 x + 16 are opposite to each other, find the value of x 2 + 2XY + y 2

Given that X-Y + 1 and x 2 + 8 x + 16 are opposite to each other, find the value of x 2 + 2XY + y 2

Given that │ X-Y + 1 │ and X2 + 8x + 16 are opposite to each other, find the value of x2 + 2XY + Y2. X-Y + 1 = 0; (1) (x + 4) = 0; X = - 4; y = - 4 + 1 = - 3; ‖ x2 + 2XY + y2 = (x + y) &# 178; = (- 4-3) &# 178; = 49; I'm glad to answer for you, skyhunter 002 will answer for you.
