Polynomial Product A: A Deep Dive

Polynomial product A, represented as (4x2−4x)(x2−4)(4x^2 - 4x)(x^2 - 4), presents a fascinating challenge. Let's dissect this expression, meticulously multiplying the two polynomials to reveal its underlying structure. Our arsenal includes the distributive property, a cornerstone of polynomial multiplication, which dictates that each term within the first polynomial must be multiplied by every term within the second polynomial. Prepare to witness the intricate dance of terms as we embark on this mathematical expedition.

Applying the distributive property, we embark on a systematic multiplication process:

  • Multiply 4x24x^2 by (x2−4)(x^2 - 4): 4x2∗x2−4x2∗4=4x4−16x24x^2 * x^2 - 4x^2 * 4 = 4x^4 - 16x^2
  • Multiply −4x-4x by (x2−4)(x^2 - 4): −4x∗x2+(−4x)∗(−4)=−4x3+16x-4x * x^2 + (-4x) * (-4) = -4x^3 + 16x

Combining these partial products, we arrive at the expanded form of polynomial product A:

4x4−16x2−4x3+16x4x^4 - 16x^2 - 4x^3 + 16x

To present this polynomial in its most elegant form, we arrange the terms in descending order of their exponents, adhering to the standard convention:

Polynomial Product A, expressed as (4x2−4x)(x2−4)(4x^2 - 4x)(x^2 - 4), beckons us to explore the realm of polynomial multiplication. To unveil its simplified form, we must employ the distributive property, ensuring that each term within the first factor interacts with every term in the second factor. This meticulous process forms the bedrock of polynomial expansion.

The distributive property, a cornerstone of algebra, dictates the following:

(a+b)(c+d)=a(c+d)+b(c+d)=ac+ad+bc+bd(a + b)(c + d) = a(c + d) + b(c + d) = ac + ad + bc + bd

Applying this principle to Polynomial Product A, we embark on a systematic multiplication:
