Answer 2

Simplifying the Expression and Finding Its Value

To simplify the given expression and find its value when \( b = \frac{1}{2} \), we can follow these steps:

1. Substitute \( b = \frac{1}{2} \) into the expression. 2. Simplify the expression using the substituted value.

Let's proceed with these steps.

Substituting \( b = \frac{1}{2} \) into the Expression

Substituting \( b = \frac{1}{2} \) into the given expression: \[ (3-\frac{1}{2})(3+\frac{1}{2})(9+(\frac{1}{2})^2) + (4+(\frac{1}{2})^2)^2 \]

Simplifying the Expression

Simplifying the expression with the substituted value: \[ (2\frac{1}{2})(3\frac{1}{2})(9+(\frac{1}{2})^2) + (4+(\frac{1}{2})^2)^2 \] \[ (2\frac{1}{2})(3\frac{1}{2})(9+\frac{1}{4}) + (4+\frac{1}{4})^2 \] \[ \frac{5}{2} \times \frac{7}{2} \times \frac{37}{4} + (\frac{17}{4})^2 \] \[ \frac{35}{4} \times \frac{37}{4} + \frac{289}{16} \] \[ \frac{1295}{16} + \frac{289}{16} \] \[ \frac{1584}{16} \] \[ 99 \]

The value of the expression when \( b = \frac{1}{2} \) is 99.
