Solve the equation using factoring or the quadratic formula, whichever is appropriate. make sure to simplify your answers.

0.01y2−0.02y−0.04=0

Step-by-step explanation:

Eliminate the fractions first.  Multiply all terms by 100, obtaining:

y^2 - 2y  + 4 = 0.  The quadratic equation is the faster method here.  The discriminant, b^2 - 4ac, is 4 -4(1)(4), or 4(-15).  Because this result is negative, the equation has two complex roots:

      -(-2) ± √(4)(-15)

x =

                 2

or

      2 ± 2i√15

x =

             2

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
