is x= -3 a solution to the equation -3x^2 - 9x = 3

Answer 1

To check if x = -3 is a solution to the equation -3x^2 - 9x = 3, we substitute -3 for x in the equation and see if both sides are equal:

-3(-3)^2 - 9(-3) = 3

-3(9) + 27 = 3

-27 + 27 = 3

0 = 3

Since 0 is not equal to 3, x = -3 is not a solution to the equation -3x^2 - 9x = 3.
