Question

factories 2y(3)+y(2)-2y--1

Answer 1

Answer:

this is the answer of this question.

Answer 2

Correct Question

2y³ + y² - 2y - 1

Factories it

Solution

→ 2y³ + y² - 2y - 1

→ y²(2y + 1) - 1(2y + 1)

→ (2y + 1)(y² - 1)

★ Applying identity :

a² - b² = (a + b)(a - b)

→ (2y + 1)[(y)² - (1)²]

→ (2y + 1)[(y + 1)(y - 1)]

→ (2y + 1)(y + 1)(y - 1)
