9 x^{2} - 16 x = 4

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

Decimal Notation

x = 2, x = - 0.22222 \dots

Solution steps

9 x^{2} - 16 x = 4

Move

4

to the left side

9 x^{2} - 16 x - 4 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 16 ) \pm ( - 16 ) ^{2} - 4 \cdot 9 ( - 4 )}{2 \cdot 9}

(- 16)^{2} - 4 \cdot 9 (- 4) = 20

x_{1, 2} = \frac{- ( - 16 ) \pm 20}{2 \cdot 9}

Separate the solutions

x_{1} = \frac{- ( - 16 ) + 20}{2 \cdot 9}, x_{2} = \frac{- ( - 16 ) - 20}{2 \cdot 9}

x = \frac{- ( - 16 ) + 20}{2 \cdot 9} : 2

x = \frac{- ( - 16 ) - 20}{2 \cdot 9} : - \frac{2}{9}

The solutions to the quadratic equation are:

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

x, - x^{2} + x (1 - h) = 0

(x + 1)^{2} = (x - 7)^{2} + x^{2}

F, V = π (r^{2} + F^{2})

7 - 2 x^{2} = - 25

2 x^{2} + 9 x = - 10
