Question

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

Answer 1

Step-by-step explanation:

${x}^{2} + ax - 3 = 0$

$x = - 3$

${( - 3)}^{2} + a( - 3) - 3 = 0$

$9 - 3a - 3 = 0$

$6 - 3a = 0$

$- 3a = - 6$

$a = \frac{ - 6}{ - 3}$

$a = 2$

Answer 2

Answer:

the value of a is 2

Step-by-step explanation:

(-3)^2 + (-3)x - 3 = 0

9 -3x -3 = 0

3x = 6

x = 2
