0 = 40 x + 75 - 3 x^{2}

x = - \frac{5}{3}, x = 15

Solution steps

0 = 40 x + 75 - 3 x^{2}

Switch sides

40 x + 75 - 3 x^{2} = 0

Write in the standard form

a x^{2} + b x + c = 0

- 3 x^{2} + 40 x + 75 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 40 \pm 4 0 ^{2} - 4 ( - 3 ) \cdot 75}{2 ( - 3 )}

4 0^{2} - 4 (- 3) \cdot 75 = 50

x_{1, 2} = \frac{- 40 \pm 50}{2 ( - 3 )}

Separate the solutions

x_{1} = \frac{- 40 + 50}{2 ( - 3 )}, x_{2} = \frac{- 40 - 50}{2 ( - 3 )}

x = \frac{- 40 + 50}{2 ( - 3 )} : - \frac{5}{3}

x = \frac{- 40 - 50}{2 ( - 3 )} : 15

The solutions to the quadratic equation are:

x = - \frac{5}{3}, x = 15

\frac{4}{3} x + 8 \geq 3 (1 - \frac{1}{3 x})

g^{\frac{4}{7}} \cdot g^{\frac{3}{7}}

\frac{5}{6} x - 2 = \frac{7}{8}

2 x^{2} - 11 x - 2 = 0

2 k^{2} + 22 k = 74
