- 16 t^{2} + 70 t - 55 = 0

t = \frac{35 - 345}{16}, t = \frac{35 + 345}{16}

Decimal Notation

t = 1.02661 \dots, t = 3.34838 \dots

Solution steps

- 16 t^{2} + 70 t - 55 = 0

Solve with the quadratic formula

t_{1, 2} = \frac{- 70 \pm 7 0 ^{2} - 4 ( - 16 ) ( - 55 )}{2 ( - 16 )}

7 0^{2} - 4 (- 16) (- 55) = 2345

t_{1, 2} = \frac{- 70 \pm 2 345}{2 ( - 16 )}

Separate the solutions

t_{1} = \frac{- 70 + 2 345}{2 ( - 16 )}, t_{2} = \frac{- 70 - 2 345}{2 ( - 16 )}

t = \frac{- 70 + 2 345}{2 ( - 16 )} : \frac{35 - 345}{16}

t = \frac{- 70 - 2 345}{2 ( - 16 )} : \frac{35 + 345}{16}

The solutions to the quadratic equation are:

t = \frac{35 - 345}{16}, t = \frac{35 + 345}{16}

4 (2 y + 6) = - 4 y

25 x^{2} = 4

- 2 (x + 4) + 6 = - 3

3 x - 4 > x + 6

\frac{5}{4} + \frac{3 x}{2} = \frac{7 x}{6}
