t^{2} - t - 12 = 0

t = 4, t = - 3

Solution steps

t^{2} - t - 12 = 0

Solve with the quadratic formula

t_{1, 2} = \frac{- ( - 1 ) \pm ( - 1 ) ^{2} - 4 \cdot 1 \cdot ( - 12 )}{2 \cdot 1}

(- 1)^{2} - 4 \cdot 1 \cdot (- 12) = 7

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

Separate the solutions

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

t = \frac{- ( - 1 ) + 7}{2 \cdot 1} : 4

t = \frac{- ( - 1 ) - 7}{2 \cdot 1} : - 3

The solutions to the quadratic equation are:

t = 4, t = - 3

x, x^{2} - 4 x + 1 = 0

x^{2} - 6 x + 1

0 = 3 x^{2} - 12 x - 15

19 x = 7 - 6 x^{2}

4^{2} = 2^{2} + x^{2}
