m^{2} - 14 m - 20 = 0

m = 7 + 69, m = 7 - 69

Decimal Notation

m = 15.30662 \dots, m = - 1.30662 \dots

Solution steps

m^{2} - 14 m - 20 = 0

Solve with the quadratic formula

m_{1, 2} = \frac{- ( - 14 ) \pm ( - 14 ) ^{2} - 4 \cdot 1 \cdot ( - 20 )}{2 \cdot 1}

(- 14)^{2} - 4 \cdot 1 \cdot (- 20) = 269

m_{1, 2} = \frac{- ( - 14 ) \pm 2 69}{2 \cdot 1}

Separate the solutions

m_{1} = \frac{- ( - 14 ) + 2 69}{2 \cdot 1}, m_{2} = \frac{- ( - 14 ) - 2 69}{2 \cdot 1}

m = \frac{- ( - 14 ) + 2 69}{2 \cdot 1} : 7 + 69

m = \frac{- ( - 14 ) - 2 69}{2 \cdot 1} : 7 - 69

The solutions to the quadratic equation are:

m = 7 + 69, m = 7 - 69

(3 - 2 x)^{2} - 4 (6 - x) + 3 x = - 9

3 x^{2} + 4 x^{2} = 6 x + 9

x^{2} + 35 = - 12 x - 1

x, (x - 2)^{2} + ((x + 3) - 4)^{2} = 25

a^{2} + 7^{2} = 1 0^{2}
