x^{2} - 5 x - 16 = 0

x = \frac{5 + 89}{2}, x = \frac{5 - 89}{2}

Solution steps

x^{2} - 5 x - 16 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 5 ) \pm ( - 5 ) ^{2} - 4 \cdot 1 \cdot ( - 16 )}{2 \cdot 1}

(- 5)^{2} - 4 \cdot 1 \cdot (- 16) = 89

x_{1, 2} = \frac{- ( - 5 ) \pm 89}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 5 ) + 89}{2 \cdot 1}, x_{2} = \frac{- ( - 5 ) - 89}{2 \cdot 1}

x = \frac{- ( - 5 ) + 89}{2 \cdot 1} : \frac{5 + 89}{2}

x = \frac{- ( - 5 ) - 89}{2 \cdot 1} : \frac{5 - 89}{2}

The solutions to the quadratic equation are:

x = \frac{5 + 89}{2}, x = \frac{5 - 89}{2}

x, 4 x^{2} + 13 k = 2 k x

X^{2} = 7^{2} + 2 4^{2}

2 x^{2} - 56 = - 9 x

(9 - y)^{2} + y^{2} = 53

m^{2} - 1.04 = 1.16
