use the distributive property and solve
To expand the expression (x+5)(3x^2 - 2x + 1), we can use the distributive property. This means that we'll multiply each term in the first parentheses by each term in the second parentheses.
Step 1: Multiply the first term of the first parentheses (x) by each term in the second parentheses:
x * (3x^2 - 2x + 1) = 3x^3 - 2x^2 + x
Step 2: Multiply the second term of the first parentheses (+5) by each term in the second parentheses:
5 * (3x^2 - 2x + 1) = 15x^2 - 10x + 5
Step 3: Combine the results from step 1 and step 2 to get the fully expanded expression:
(x+5)(3x^2 - 2x + 1) = 3x^3 - 2x^2 + x + 15x^2 - 10x + 5
Simplifying the expression further, we can combine like terms:
3x^3 + (15x^2 - 2x^2) + (x - 10x) + 5
3x^3 + 13x^2 - 9x + 5
Therefore, (x+5)(3x^2 - 2x + 1) expands to 3x^3 + 13x^2 - 9x + 5.
