Best ResponseYou've already chosen the best response.0You can factor by grouping when the polynomial has four terms, but no single GCF. You should be able to arrange the terms into two groups, each with a unique GCF. When you factor the two groups you'll have the same pair of terms left. 25x³ + 5x² + 30x + 6 (25x³ + 5x²) + (30x + 6) GCF of first group is 5x² and for second group it's 6. 5x²(5x + 1) + 6(5x + 1) Now there's a gcf of (5x + 1) so we can write (5x + 1)(5x² + 6)
