a^{2} - 3.4 a + 1.2 = 0

a = 3, a = \frac{2}{5}

Decimal Notation

a = 3, a = 0.4

Solution steps

a^{2} - 3.4 a + 1.2 = 0

Multiply both sides by

10

10 a^{2} - 34 a + 12 = 0

Solve with the quadratic formula

a_{1, 2} = \frac{- ( - 34 ) \pm ( - 34 ) ^{2} - 4 \cdot 10 \cdot 12}{2 \cdot 10}

(- 34)^{2} - 4 \cdot 10 \cdot 12 = 26

a_{1, 2} = \frac{- ( - 34 ) \pm 26}{2 \cdot 10}

Separate the solutions

a_{1} = \frac{- ( - 34 ) + 26}{2 \cdot 10}, a_{2} = \frac{- ( - 34 ) - 26}{2 \cdot 10}

a = \frac{- ( - 34 ) + 26}{2 \cdot 10} : 3

a = \frac{- ( - 34 ) - 26}{2 \cdot 10} : \frac{2}{5}

The solutions to the quadratic equation are:

a = 3, a = \frac{2}{5}

x^{2} - 7 x - 170 = 0

2 x^{2} - 7 x - 32 = 0

2 x^{2} + 5 x - 14 = 0

x^{2} - 5 x + 2 = 3 - 2 x

r^{2} - \frac{4}{9} = 0
