Solve 500.0v^2 - 2000.0 = 6000

500.0 v^{2} - 2000.0 = 6000

Step by step

  1. 500.0 v^{2} - 2000.0 = 6000

    Start from the equation as given.

  2. 500.0 v^{2} - 8000.0 = 0

    Bring everything to one side and collect like terms so the right-hand side is 0.

  3. a = 500.0,\quad b = 0.0,\quad c = -8000.0

    Read off the coefficients of the standard form ax² + bx + c = 0.

  4. 8000.0 \left(0.25 v - 1.0\right) \left(0.25 v + 1.0\right) = 0

    Factor the quadratic into two linear factors.

  5. 0.25 v + 1.0 = 0 \;\Rightarrow\; v = -4.0

    A product is zero only when one of its factors is zero (zero-product property).

  6. 0.25 v - 1.0 = 0 \;\Rightarrow\; v = 4.0

    A product is zero only when one of its factors is zero (zero-product property).

Reveal the answer
v = -4.0 \quad\text{or}\quad v = 4.0
