Question

Please check the expressions that represent a perfect square trinomial.

Answer 1

Given :-

• To check for the perfect square trinomials.

Answer :-

As we know that the general form is ,

$\sf\longrightarrow$ p(x) = ax² + bx + c .

So from the given options , the equations which are perfect square is ,

$\sf\longrightarrow$ x² - 2xy + y² = ( x-y)²

And ,

$\sf\longrightarrow$ x² + 2xy + y² = ( x+ y)²

This is our required answer .
