Question

If x= -3 is the factor of x²+ax-3 then value of a is
[2,-1, 3, -2]​

Answer 1

Answer:

2

Step-by-step explanation:

9-3x-3 = 0

6-3x = 0

finally

x = 2

Answer 2

Answer :

• The value of a is 2.

Given :

• x = -3 is a factor of x² + ax - 3.

To Find :

• Value of a.

Solution :

Put the value of x in the equation

Now,

According to question :

→ x² + ax - 3 = 0

→ (-3)² + a (-3) - 3 = 0

→ 9 - 3a - 3 = 0

→ 9 - 3 - 3a = 0

→ 6 - 3a = 0

→ 6 = 3a

→ a = 6/3

→ a = 2

Hence, the value of a is 2.
