Question

factor completely.

\\10f^3 - 14f - 7 + 5f^2\\

Explanation:

⚡ Using what you learned: Factoring by Grouping

Step 1: Rearrange terms

$$ 10f^3 + 5f^2 - 14f - 7 $$

Step 2: Group and factor out GCF

$$ 5f^2(2f + 1) - 7(2f + 1) $$

Step 3: Factor out common binomial

$$ (2f + 1)(5f^2 - 7) $$

Answer:

$$ (2f + 1)(5f^2 - 7) $$
