# Write the Following Square of Binomial as Trinomial: (X2 − Ay)2 - Mathematics

Write the following square of binomial as trinomial:  (x2 − ay)2

#### Solution

We will use the identities

$\left( a + b \right)^2 = a^2 + 2ab + b^2 \text { and } \left( a - b \right)^2 = a^2 - 2ab + b^2$ to convert the squares of binomials as trinomials.

$\left( x^2 - ay \right)^2$

$= \left( x^2 \right)^2 - 2 x^2 \left( ay \right) + \left( ay \right)^2$

$= x^4 - 2 x^2 ay + a^2 y^2$
