Question

Write the identity for (x+y)²
Write the identity for (xx-y2
Write the identity for x² - y²
Write the additive inverse of
-5/9 ii -6/5
Find any five rational numbers between
-5/9&5/8

​

Answer 1

Step-by-step explanation:

I) (x+y)² = x² + y² + 2*x*y

II) x² - y² = (x+y)(x-y)

III) I) 5/9 II) 6/5

IV) -20/72, -10/72, 0/72, 10/72, 20/72

Answer 2

MARK ME AS THE BRAINLIEST

ANSWER:

1. (x+y)^2 = x^2+y^2+2xy
2. (x+y)^2 = x^2+y^2-2xy
3. x^2-y^2 = (x-y)(x+y)
4. a.5/9 b.6/5
5. -5/9 & 5/8 = -40/72 & 45/72(LCM)

so, five rational numbers are

-39/72, -38/72, -36/72, -35/72 and -34/72
