Question

3. Write four rational numbers equivalent to the following rational numbers.
1)-2/7
2)4/9​

Answer 1

Step-by-step explanation:

For Example: The identity (x+y)2 = x2+2xy+y2 will be the same for all values of x and y.

The standard algebraic identities are:

(x – y) (x – z) = x2 – (y + z) x + yz.

Example of Trinomials Identity : (a + b + c)2 = a2 + b2 + c2 + 2 · a · b + 2 · a · c + 2 · b · c.
