x^{2} - 10 x = - 18

x = 5 + 7, x = 5 - 7

Decimal Notation

x = 7.64575 \dots, x = 2.35424 \dots

Solution steps

x^{2} - 10 x = - 18

Move

18

to the left side

x^{2} - 10 x + 18 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 10 ) \pm ( - 10 ) ^{2} - 4 \cdot 1 \cdot 18}{2 \cdot 1}

(- 10)^{2} - 4 \cdot 1 \cdot 18 = 27

x_{1, 2} = \frac{- ( - 10 ) \pm 2 7}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 10 ) + 2 7}{2 \cdot 1}, x_{2} = \frac{- ( - 10 ) - 2 7}{2 \cdot 1}

x = \frac{- ( - 10 ) + 2 7}{2 \cdot 1} : 5 + 7

x = \frac{- ( - 10 ) - 2 7}{2 \cdot 1} : 5 - 7

The solutions to the quadratic equation are:

x = 5 + 7, x = 5 - 7

8 a^{4} b^{4} - 28 a^{3} b^{3} + 4 a^{2} b^{2}

6 X - 5 \leq 13

4 n^{2} - 9

2 x^{3} - 12 x^{2} + 18 x

16 < x - 7 < 16
