The solutions to the equation x^2-20x+85=-6 are x=13,x=7

Find the zeros of x^2-20x+85=-6

The zeros of x^2-20x+85=-6 are x=13,x=7

x^{2} - 20 x + 85 = - 6

x = 13, x = 7

Solution steps

x^{2} - 20 x + 85 = - 6

Move

6

to the left side

x^{2} - 20 x + 91 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 20 ) \pm ( - 20 ) ^{2} - 4 \cdot 1 \cdot 91}{2 \cdot 1}

(- 20)^{2} - 4 \cdot 1 \cdot 91 = 6

x_{1, 2} = \frac{- ( - 20 ) \pm 6}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 20 ) + 6}{2 \cdot 1}, x_{2} = \frac{- ( - 20 ) - 6}{2 \cdot 1}

x = \frac{- ( - 20 ) + 6}{2 \cdot 1} : 13

x = \frac{- ( - 20 ) - 6}{2 \cdot 1} : 7

The solutions to the quadratic equation are:

x = 13, x = 7

3 m^{3} - m^{2} + 9 m - 3

30 \cdot \frac{1}{3}

\frac{x ^{3} - 6 x ^{2}}{x - 2} > 0

\frac{- 5 m ^{- 5}}{- 3 ( m ^{- 5} ) ^{4}}

\frac{40 - x}{14} = \frac{x}{15} + \frac{x}{10}
