We use the identity with a = 7/5 x and b = 3/2 y. Squaring the fractional coefficients and multiplying two with both terms yields the expanded expression with simplified fraction terms.
Using the identity (a + b) square = a square + 2ab + b square, expand (7/5 x + 3/2 y) square

We expand this fractional binomial using the standard addition square formula. Here, our first term a is 7/5 x and our second term b is 3/2 y. The square of 7/5 x is 49/25 x square, and the square of 3/2 y is 9/4 y square. The middle term is calculated as two times 7/5 x times 3/2 y, which simplifies cleanly to 21/5 xy.
