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
