Final answer:
To expand (3x-1)(x²+2x-3), use the distributive property (FOIL method) to multiply each term in the first polynomial by each term in the second, resulting in 3x³ + 5x² - 11x + 3 after combining like terms.
Step-by-step explanation:
Expanding the Expression
To expand the expression (3x - 1)(x² + 2x - 3), you use the distributive property, also known as the FOIL method (First, Outer, Inner, Last), to multiply each term in the first polynomial by each term in the second polynomial.
- Multiply 3x by x² to get 3x³.
- Multiply 3x by 2x to get 6x².
- Multiply 3x by -3 to get -9x.
- Multiply -1 by x² to get -x².
- Multiply -1 by 2x to get -2x.
- Multiply -1 by -3 to get 3.
Combining like terms, we get the expanded form 3x³ + 5x² - 11x + 3.
