10 x^{2} + 23 x = 21

x = \frac{7}{10}, x = - 3

Decimal Notation

x = 0.7, x = - 3

Solution steps

10 x^{2} + 23 x = 21

Move

21

to the left side

10 x^{2} + 23 x - 21 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 23 \pm 2 3 ^{2} - 4 \cdot 10 ( - 21 )}{2 \cdot 10}

2 3^{2} - 4 \cdot 10 (- 21) = 37

x_{1, 2} = \frac{- 23 \pm 37}{2 \cdot 10}

Separate the solutions

x_{1} = \frac{- 23 + 37}{2 \cdot 10}, x_{2} = \frac{- 23 - 37}{2 \cdot 10}

x = \frac{- 23 + 37}{2 \cdot 10} : \frac{7}{10}

x = \frac{- 23 - 37}{2 \cdot 10} : - 3

The solutions to the quadratic equation are:

x = \frac{7}{10}, x = - 3
