Answer:

x is equal to -3

Step-by-step explanation:

If you have a lot of problems with decimal coefficients (I know I do), you can get rid of them first. Just multiply both sides of the equation by 10:

.3x² + 1 = .1

3x² + 10x = x

Then note that each term is also divisible by x. If we factor that out, we get:

3x + 10 = 1

Which we can easily solve for x:

3x = -9

x = -3
