(q)=20+2q-sqrt(q^2-80)

(q) = 20 + 2 q - q^{2} - 80

q = - 12

Solution steps

(q) = 20 + 2 q - q^{2} - 80

Remove square roots

q^{2} + 40 q + 400 = q^{2} - 80

Solve

q^{2} + 40 q + 400 = q^{2} - 80 : q = - 12

q = - 12

Verify Solutions:

q = - 12

True

The solution is

q = - 12

x + 3 = 4 - 5 x + 1

\frac{3}{2} + \frac{3}{6} + \frac{3}{12} + \frac{3}{20} = n^{0.75}

x^{\frac{3}{2}} + 4 x^{- 1} - 5 x^{0} = 4

9 x^{2} - 6 x + 1 = 5

6 4 x^{2} = 8
