Question

Factorise : 2y² - y - 6.​

Answer 1

Answer:Hi

Step-by-step explanation:

2y² + y − 6

when faced with ax² + bx + c then find factors of the product ac that sum to b and use them to factor via grouping.

ac = 2 * -6 = -12

4 * -3 = -12

4 + -3 = 1 = b

⇒ 2y² + 4y − 3y − 6

⇒ 2y(y + 2) − 3(y + 2)

⇒ (y + 2)(2y − 3)
