Sophia’s work factoring a perfect square trinomial is (4x+5)^{2}.

Step-by-step explanation:

We have,

16x^2 – 40x + 25

= (4x)^2 - 2(4x)(5) + 5^{2}

Using the algebraic identity,

(a+b)^{2}=a^{2}+2ab+b^{2}

= (4x)^2 - 2(4x)(5) + 5^{2}

= (4x+5)^{2} ≠ ((x + 5)^2

Thus, Sophia’s work factoring a perfect square trinomial is (4x+5)^{2}.
