39.2 t - 4.9 t^{2} = 0

t = 0, t = 8

Solution steps

39.2 t - 4.9 t^{2} = 0

Multiply both sides by

10

392 t - 49 t^{2} = 0

Write in the standard form

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

- 49 t^{2} + 392 t = 0

Solve with the quadratic formula

t_{1, 2} = \frac{- 392 \pm 39 2 ^{2} - 4 ( - 49 ) \cdot 0}{2 ( - 49 )}

39 2^{2} - 4 (- 49) \cdot 0 = 392

t_{1, 2} = \frac{- 392 \pm 392}{2 ( - 49 )}

Separate the solutions

t_{1} = \frac{- 392 + 392}{2 ( - 49 )}, t_{2} = \frac{- 392 - 392}{2 ( - 49 )}

t = \frac{- 392 + 392}{2 ( - 49 )} : 0

t = \frac{- 392 - 392}{2 ( - 49 )} : 8

The solutions to the quadratic equation are:

t = 0, t = 8

36 y^{2} - 54 y - 16 = 0

4 p^{2} - 5 p - 51 = 0

2 x^{(2)} + 3 = 6 x

x, f = u (x^{2})

- x^{2} - 2 x + 8
