5 x^{2} - 10 x - 13 = 9 x - 9

x = 4, x = - \frac{1}{5}

Decimal Notation

x = 4, x = - 0.2

Solution steps

5 x^{2} - 10 x - 13 = 9 x - 9

Move

9

to the left side

5 x^{2} - 10 x - 4 = 9 x

Move

9 x

to the left side

5 x^{2} - 19 x - 4 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 19 ) \pm ( - 19 ) ^{2} - 4 \cdot 5 ( - 4 )}{2 \cdot 5}

(- 19)^{2} - 4 \cdot 5 (- 4) = 21

x_{1, 2} = \frac{- ( - 19 ) \pm 21}{2 \cdot 5}

Separate the solutions

x_{1} = \frac{- ( - 19 ) + 21}{2 \cdot 5}, x_{2} = \frac{- ( - 19 ) - 21}{2 \cdot 5}

x = \frac{- ( - 19 ) + 21}{2 \cdot 5} : 4

x = \frac{- ( - 19 ) - 21}{2 \cdot 5} : - \frac{1}{5}

The solutions to the quadratic equation are:

x = 4, x = - \frac{1}{5}

r, A = 2 π r^{2} + 2 π r h

(x - 7)^{2} = 11

4 x^{2} - 10 = 4 x - 7

y^{2} - 2 y

y (y + 4) = - 4
