Thus, the factored form is $\boxed(4x - 5)^2$. - Deep Underground Poetry

Understanding the Context

Factoring transforms a polynomial into a product of simpler expressions. In the case of $(4x - 5)^2$, the factorization reveals a repeated binomial, which is an expression of the form $(a - b)^2 = a^2 - 2ab + b^2$. More importantly, this form highlights symmetry and key features such as roots, symmetry axes, and key coefficients — powerful insights for graphing, solving, and simplifying.

Breaking Down $(4x - 5)^2$

Begin by expanding the factored form using the binomial square formula:

$$
(4x - 5)^2 = (4x)^2 - 2(4x)(5) + (5)^2 = 16x^2 - 40x + 25
$$

Key Insights

However, its true power lies in recognizing that this factorization stems from identifying a repeated binomial: $4x - 5$ appears twice multiplied. This squared structure conveys:

• Double Root: The expression equals zero when $4x - 5 = 0$, or $x = rac{5}{4}$, and because of the square, this root has multiplicity two—meaning the graph touches but does not cross the x-axis at this point.
  
• Efficient Simplification: Factoring eliminates the need for expanding when tackling quadratic equations, inequalities, or integrals.
  
• Clear Structure for Analysis: In calculus and calculus-based problems, knowing the factored form suggests the vertex, axis of symmetry, and concavity at a glance.

When and Why to Use This Form

You encountered the factored form $oxed{(4x - 5)^2}$ when simplifying quadratic expressions or solving equations like $ (4x - 5)^2 = 0 $. This form isn’t merely decorative — it’s a strategic choice that supports quicker, clearer computational steps and deeper algebraic understanding.

Conclusion

Final Thoughts

The factored form $(4x - 5)^2$ is more than notation — it’s a window into the structure and behavior of quadratic expressions.
