4v^2+25=-20v — step-by-step solution

⚠ 4v is read as the product 4*v: for a power, write 4^v‖20v is read as the product 20*v: for a power, write 20^v

Let's solve in

ℝ

4 v^{2} + 25 = -20 v

You can transform this expression into:

{(2 v + 5)}^{2}

{(2 v + 5)}^{2} = 0

means that:

2 v + 5 = 0

2 v = -5

▶Solution obtained:

v = - \frac{5}{2}

The numeric value of:

v = - \frac{5}{2}

equals:

▷

v = -2.5
