Para factorizar la expresión cuadrática \( 4x^{2} - 5^{2}x + \frac{9}{25} \), primero observamos que se puede escribir como un trinomio de la forma \( ax^2 + bx + c \). Aquí, podemos aplicar la fórmula de factorización o intentar agrupar. Observando que \( 4x^{2} \) es un cuadrado perfecto, y que también \( \left(\frac{3}{5}\right)^2 = \frac{9}{25} \), reconocemos que podemos reorganizar y agrupar adecuadamente para obtener: \[ 4x^{2} - 5x + \frac{9}{25} = (2x - \frac{3}{5})^2 \] Ahora hemos factorizado la expresión, ¡y todo gracias a los cuadrados perfectos! Para asegurarte que la factorización es correcta, puedes realizar la expansión. Al hacerlo, notarás que los términos coinciden, así que el resultado final es: \[ (2x - \frac{3}{5})^2 \] ¡Y voilà! Hemos descompuesto la expresión de manera correcta.

An animal breeder can buy four types of food for Vietnamese pot-bellied pigs. Each case of Brand A contains 25 units of fiber, 40 units of protein, and 40 units of fat. Each case of Brand B contains 100 units of fiber, 130 units of protein, and 110 units of fat. Each case of Brand C contains 275 units of fiber, 350 units of protein, and 310 units of fat. Each case of Brand D contains 200 units of fiber, 260 units of protein, and 200 units of fat. How many cases of each brand should the breeder mix together to obtain a food that provides 3975 units of fiber, 5100 units of protein, and 4440 units of fat? Let \( x \) represent the number of cases of Brand A, y represent the number of cases of Brand B, z represent the number of cases of Brand C, and w represent be the number of cases of Brand \( D \). There are four ways in which the breeder can mix brands to obtain a food that provides 3975 units of fiber, 5100 units of protein, and 4440 units of fat. If \( w=0 \), the solution is \( (0,15,9,0) \). If \( w=1 \), the solution is \( (\square, \square, \square, 1) \).

An investor plans to put a total of \( \$ 110,000 \) in a money market account, a bond fund, an international stock fund, and a domestic stock fund. She wants \( 60 \% \) of her investment to be conservative (money market and bonds). The investor wants the amount in international stocks to be one-fourth the amount in domestic stocks. Finally, the investor needs an annual return of \( \$ 4,400 \). Assuming the investor gets annual returns of \( 2.5 \% \) on the money market account, \( 3.5 \% \) on the bond fund, \( 4 \% \) on the international stock fund, and \( 6 \% \) on the domestic stock fund, how much should the investor put in each investment? The investor should put \( \$ 8800 \) in the international stock fund. (Type a whole number.) The investor should put \( \$ \square \) in domestic stock fund. (Type a whole number.)
