0 = - 2.7 t^{2} + 30 t + 6.5

t = - \frac{- 50 + 7 55}{9}, t = \frac{50 + 7 55}{9}

Solution steps

0 = - 2.7 t^{2} + 30 t + 6.5

Multiply both sides by

10

0 = - 27 t^{2} + 300 t + 65

Switch sides

- 27 t^{2} + 300 t + 65 = 0

Solve with the quadratic formula

t_{1, 2} = \frac{- 300 \pm 30 0 ^{2} - 4 ( - 27 ) \cdot 65}{2 ( - 27 )}

30 0^{2} - 4 (- 27) \cdot 65 = 4255

t_{1, 2} = \frac{- 300 \pm 42 55}{2 ( - 27 )}

Separate the solutions

t_{1} = \frac{- 300 + 42 55}{2 ( - 27 )}, t_{2} = \frac{- 300 - 42 55}{2 ( - 27 )}

t = \frac{- 300 + 42 55}{2 ( - 27 )} : - \frac{- 50 + 7 55}{9}

t = \frac{- 300 - 42 55}{2 ( - 27 )} : \frac{50 + 7 55}{9}

The solutions to the quadratic equation are:

t = - \frac{- 50 + 7 55}{9}, t = \frac{50 + 7 55}{9}

f^{2} + 7 f + 10 = 0

(- 5)^{2} + (2)^{2} = D^{2}

3 x (x + 2) = 6 (x - 3)

- 3 x^{2} - 48 x = 0

- 2 x^{2} + 7 x + 15 = 0
