The factorisation of the given expressions is as follows;
- a) p²y²– 2py + 1 = (py -1)²
- b) a²y² -2aby +b² = (ay - b)²
<h3>Factorization using identities</h3>
The given identity is;
From the given identity, we can conclude that;
In the expression (a);
- py represents a in the identity and 1 represents b in the identity.
In the expression (b);
- ay represents a in the identity and b represents b in the identity.
Hence, the factorised expressions are as represented above.
