9 x^{2} + 14 = 65 x

x = 7, x = \frac{2}{9}

Decimal Notation

x = 7, x = 0.22222 \dots

Solution steps

9 x^{2} + 14 = 65 x

Move

65 x

to the left side

9 x^{2} + 14 - 65 x = 0

Write in the standard form

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

9 x^{2} - 65 x + 14 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 65 ) \pm ( - 65 ) ^{2} - 4 \cdot 9 \cdot 14}{2 \cdot 9}

(- 65)^{2} - 4 \cdot 9 \cdot 14 = 61

x_{1, 2} = \frac{- ( - 65 ) \pm 61}{2 \cdot 9}

Separate the solutions

x_{1} = \frac{- ( - 65 ) + 61}{2 \cdot 9}, x_{2} = \frac{- ( - 65 ) - 61}{2 \cdot 9}

x = \frac{- ( - 65 ) + 61}{2 \cdot 9} : 7

x = \frac{- ( - 65 ) - 61}{2 \cdot 9} : \frac{2}{9}

The solutions to the quadratic equation are:

x = 7, x = \frac{2}{9}

x^{2} - 5 x + n + 2 = 0

- (x - 2)^{2} + 16 = 0

6 - x^{2} + 8 x = 5 + 4 x

0 = 2.4 + 8.6 x - 4.9 \cdot x^{2}

(x + 49)^{2} = 24
