Question

2a³ - 5a + 6 factorise​

Answer 1

Answer:

bro I think your question is wrong

Answer 2

Step-by-step explanation:

putting a = -2

P(a) = 2a³-5a+6

P(-2) = 2(-2)³-5(-2)+6

= 2(-8)+10+6

= -16+16

= 0

therefore (a+2) is a factor of (2a³-5a+6)

now dividing (2a³-5a+6) by (a+2)____(see image)

factors = (a+2)(2a²-4a+3)
