Solve by completing the square. 9x = 3x^2 - 1

0 ≠ -1

x =(-9-√93)/-6=3/2+1/6√ 93 = 3.107

x =(-9+√93)/-6=3/2-1/6√ 93 = -0.107

Step-by-step explanation:

9x = 3x^2 - 1

first, lets simplify the 3x^2 to get 9x

now we have 9x = 9x - 1 right?

we are going to take 9x from both sides which leaves up with 0x = -1

which does not work in this equation.

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
