Question

If x-2 is a factor of x²+3ax-2a then find a *


please help me ! ​

Answer 1

Answer:

yes sure army we r a family

Step-by-step explanation:

Let P(x)=x

2

+3ax−2a

Given, (x−2) is a factor of P(x)

x−2=0

x=2

∴P(2)=0

⇒2

2

+3a(2)−2a=0

⇒4+4a=0

⇒a=−1

-1

can we be friends? have a good day

Answer 2

$\huge\bf\red{Answer ☃}$

Here is your answer.

If x-2 is a factor ..

So p(x)=x2+3ax-2a

q(x)=x-2=0

x=2

Therefore substituting x=2 value..

(2)2 +3a(2)-2a

4+6a-2a=0

4+4a=0

4a= -4

a= -1

I hope it will help you Army ✌️☺️

it's okay army no thanks between friends

I am sorry army for late answer

keep smiling always

have a nice day
