Question

if x=8 y=6 then simplyfy (x+y) (x+y)=x×x+2×x×y+y×y
(x+y) (x-y)=x×x- y×y

Answer 1

HELLO DEAR,


given that:-

x = 8 , y = 6


now,

(x + y)(x + y) = x×x + 2x×y + y×y

⇒(x + y)² = x² + 2xy + y²

⇒(8 + 6)² = 8² + 2×8×6 + 6²

⇒14² = 64 + 96 + 36

⇒196 = 196



★★★★★★★★★★★★★

Second ,

(x + y)(x - y) = x×x - y×y

⇒(8 + 6)(8 - 6) = 8² - 6²

⇒14 × 2 = 64 - 36

⇒28 = 28



I HOPE ITS HELP YOU DEAR,
THANKS
