The provided assignment encompasses a comprehensive set of algebraic tasks, including polynomial operations, solving equations, geometric applications, and graphing. This paper will systematically address each component, demonstrating mastery of algebraic principles and their applications to real-world contexts, notably the tissue box problem and graph interpretation.

To begin, the assignment prompts students to find the product of certain algebraic expressions. Without specific expressions provided, the general approach involves multiplication of binomials or polynomials, applying distributive properties such as FOIL (First, Outer, Inner, Last) to expand and simplify the products. For example, multiplying binomials like (x + 3)(x + 4) requires applying FOIL to obtain the quadratic form. These foundational skills set the stage for subsequent tasks involving factoring, solving quadratic equations, and graphing.

Factoring polynomials fully involves decomposing quadratic expressions into the product of simpler binomials, provided they are factorable. For instance, a quadratic like x^2 + 5x + 6 factors into (x + 2)(x + 3). Mastery of factoring is essential for solving equations by setting each factor equal to zero and finding the roots. The task also entails solving for x-intercepts/roots by factoring, which involves solving the equations obtained after factors are set to zero.

Furthermore, students are asked to find roots using the quadratic formula. The quadratic formula, x = (-b ± √(b^2 - 4ac)) / 2a, provides solutions when the quadratic cannot be factored easily or when the roots are irrational or complex. Calculating discriminants and interpreting solutions form a critical part of understanding quadratic equations' solutions.

The tissue box problem introduces practical applications of algebra. The side area calculation, A = lw, requires solving for length when area and width are known. Likewise, volume calculations involve V = lwh, with the additional condition that all measures are equal, implying the tissue box is a cube. In such cases, the volume simplifies to V = s^3, where s is the measure of one side, leading to straightforward volume determination once one dimension is known or calculated.

Graphing quadratic functions involves identifying the standard form y = ax^2 + bx + c. Coefficients a, b, and c determine the parabola's shape, position, and roots. The y-intercept is at y = c, as evaluating the function at x = 0 yields c. Roots or x-intercepts are solutions to y = 0, which can be found by factoring or the quadratic formula. The line of symmetry is x = -b / (2a), and the vertex's coordinates are at ( -b / (2a), y value corresponding to x = -b / (2a) ). Plotting the parabola involves these key points and characteristics, providing a complete graphical representation of the quadratic function.

The assignment further requires students to analyze multiple quadratic functions, extracting their coefficients, intercepts, roots, symmetry lines, and vertices systematically. Such practice supports understanding of quadratic properties and their visualization. Lastly, expanding the binomial, likely \((a + b)^n\), involves applying binomial expansion formulas, such as the Binomial Theorem, to generate the expanded polynomial.
