Question

Factor the following trinomial y²-11y+30​

Answer 1

`→ {y}^(2) - 11y + 30 \\ = {y}^(2) - 5y - 6y + 30 \\ = y(y - 5) - 6(y - 5) \\ = \boxed{(y - 5)(y - 6)}✓`

• (y - 5)(y - 6) is the right answer.

Answer 2

`y {}^(2) - 11y + 30 \\ y {}^(2) - 5y - 6y + 30 \\ (y {}^(2) - 5y) - (6y + 30) \\ y(y - 5) - 6(y - 5) \\ (y - 6)(y - 5)`
