t^{2} + 7 t - 2 = 0

t = \frac{- 7 + 57}{2}, t = \frac{- 7 - 57}{2}

Decimal Notation

t = 0.27491 \dots, t = - 7.27491 \dots

Solution steps

t^{2} + 7 t - 2 = 0

Solve with the quadratic formula

t_{1, 2} = \frac{- 7 \pm 7 ^{2} - 4 \cdot 1 \cdot ( - 2 )}{2 \cdot 1}

7^{2} - 4 \cdot 1 \cdot (- 2) = 57

t_{1, 2} = \frac{- 7 \pm 57}{2 \cdot 1}

Separate the solutions

t_{1} = \frac{- 7 + 57}{2 \cdot 1}, t_{2} = \frac{- 7 - 57}{2 \cdot 1}

t = \frac{- 7 + 57}{2 \cdot 1} : \frac{- 7 + 57}{2}

t = \frac{- 7 - 57}{2 \cdot 1} : \frac{- 7 - 57}{2}

The solutions to the quadratic equation are:

t = \frac{- 7 + 57}{2}, t = \frac{- 7 - 57}{2}
