Math Problem Statement

Activity 1. What is your Standard? Express the following polynomial functions into standard form.

  1. -10n-6-8n³ + 2n² =
  2. 1-2r⁴+5r² + 5r³ =
  3. -3b³-7b⁶-6b =
  4. -8x²+5x-4x⁴ =
  5. 5x²+4x⁶-3x⁴ =
  6. -4v⁶-5v³+6v⁴ = 7.-1+8n²+5n =
  7. 4r³-2r²+4-5r =
  8. 4v²-7+6v³ = 10.7x⁶-x²-7 =

Solution

The standard form of a polynomial function is one where the terms are ordered by degree, from the highest to the lowest power of the variable. For example, axn+bxn1++kax^n + bx^{n-1} + \dots + k where the terms are written in descending order of the powers of the variable.

Let’s put each polynomial in standard form:

  1. 10n68n3+2n2-10n - 6 - 8n^3 + 2n^2

    Standard Form: 8n3+2n210n6-8n^3 + 2n^2 - 10n - 6

  2. 12r4+5r2+5r31 - 2r^4 + 5r^2 + 5r^3

    Standard Form: 2r4+5r3+5r2+1-2r^4 + 5r^3 + 5r^2 + 1

  3. 3b37b66b-3b^3 - 7b^6 - 6b

    Standard Form: 7b63b36b-7b^6 - 3b^3 - 6b

  4. 8x2+5x4x4-8x^2 + 5x - 4x^4

    Standard Form: 4x48x2+5x-4x^4 - 8x^2 + 5x

  5. 5x2+4x63x45x^2 + 4x^6 - 3x^4

    Standard Form: 4x63x4+5x24x^6 - 3x^4 + 5x^2

  6. 4v65v3+6v4-4v^6 - 5v^3 + 6v^4

    Standard Form: 4v6+6v45v3-4v^6 + 6v^4 - 5v^3

  7. 1+8n2+5n-1 + 8n^2 + 5n

    Standard Form: 8n2+5n18n^2 + 5n - 1

  8. 4r32r2+45r4r^3 - 2r^2 + 4 - 5r

    Standard Form: 4r32r25r+44r^3 - 2r^2 - 5r + 4

  9. 4v27+6v34v^2 - 7 + 6v^3

    Standard Form: 6v3+4v276v^3 + 4v^2 - 7

  10. 7x6x277x^6 - x^2 - 7

    Standard Form: 7x6x277x^6 - x^2 - 7

Would you like any detailed explanation on these steps?

Here are some additional questions for practice:

  1. How would you convert 7y5+3yy4+27y^5 + 3y - y^4 + 2 to standard form?
  2. What is the standard form of 6x+x39+4x2-6x + x^3 - 9 + 4x^2?
  3. How do you arrange the polynomial 8a5a2+7a48a - 5a^2 + 7a^4 into standard form?
  4. If you had a polynomial 12t+9t52t3+t212t + 9t^5 - 2t^3 + t^2, what would be the standard form?
  5. How can you write 2n9n4+4n2+12n - 9n^4 + 4n^2 + 1 in standard form?

Tip: To quickly determine the standard form of any polynomial, first identify the highest power of the variable, then arrange all terms in descending order by the exponent.
