6x=9+x^2

6 x = 9 + x^{2}

x = 3

Solution steps

6 x = 9 + x^{2}

Switch sides

9 + x^{2} = 6 x

Move

6 x

to the left side

9 + x^{2} - 6 x = 0

Write in the standard form

a x^{2} + b x + c = 0

x^{2} - 6 x + 9 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 6 ) \pm ( - 6 ) ^{2} - 4 \cdot 1 \cdot 9}{2 \cdot 1}

(- 6)^{2} - 4 \cdot 1 \cdot 9 = 0

x_{1, 2} = \frac{- ( - 6 ) \pm 0}{2 \cdot 1}

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

\frac{- ( - 6 )}{2 \cdot 1} = 3

x = 3

The solution to the quadratic equation is:

x = 3

(e^{- 2 t})^{2}

6 a = - 54

x + 12 = x^{2}

(3 x - 1)^{3} - 27 x + 9

(x - 1) (x + 2) = 2 x
