(5x^2+84x)/(2sqrt(x+21))=0

\frac{5 x ^{2} + 84 x}{2 x + 21} = 0

x = 0, x = - \frac{84}{5}

Decimal Notation

x = 0, x = - 16.8

Solution steps

\frac{5 x ^{2} + 84 x}{2 x + 21} = 0

\frac{f ( x )}{g ( x )} = 0 \Rightarrow f (x) = 0

5 x^{2} + 84 x = 0

Solve

5 x^{2} + 84 x = 0 : x = 0, x = - \frac{84}{5}

x = 0, x = - \frac{84}{5}

Verify Solutions:

x = 0

True

, x = - \frac{84}{5}

True

The solutions are

x = 0, x = - \frac{84}{5}

(x - 4)^{\frac{3}{2}} = - 8

2 x + 6 - 2 x + 3 = 1

x^{2} - 5 x + 6 = 0

2 x + 4 x - 7 = x + 1
