Question

7 x square y square +252+84 x y

Answer 1

Answer:

There are two ways to solve this:

1st method:

Using formula: a²+2ab+b²=(a+b)²

=7x²y²+252+84xy

=7(x²y²+36+12xy)

=7(x²y²+12xy + 36)

=7[(xy)²+2× xy ×6 +6²)

=7(xy+6)²

Step-by-step explanation:

2nd method:

By splitting the middle term.

=7x²y²+252+84xy

=7(x²y²+36+12xy)

=7(x²y²+12xy + 36)

=7[x²y²+(6+6)xy +36)]

=7(x²y²+6xy+6xy+36)

=7[xy(xy+6)+6(xy+6)]

=7(xy+6)(xy+6)

=7(xy+6)²
