Multiplying Polynomials: (-x + 4)(3x² - 2x - 7)
This article will guide you through the process of multiplying the two polynomials: (-x + 4) and (3x² - 2x - 7).
Understanding the Process
We can use the distributive property to multiply these polynomials. This means multiplying each term in the first polynomial by each term in the second polynomial.
Steps for Multiplication
-
Distribute the first term of the first polynomial:
- -x * (3x² - 2x - 7) = -3x³ + 2x² + 7x
-
Distribute the second term of the first polynomial:
- 4 * (3x² - 2x - 7) = 12x² - 8x - 28
-
Combine the results from steps 1 and 2:
- (-3x³ + 2x² + 7x) + (12x² - 8x - 28)
-
Combine like terms:
- -3x³ + 14x² - x - 28
Final Result
Therefore, the product of (-x + 4) and (3x² - 2x - 7) is -3x³ + 14x² - x - 28.
