9 m^{2} - 34 m + 21 = 0

m = 3, m = \frac{7}{9}

Decimal Notation

m = 3, m = 0.77777 \dots

Solution steps

9 m^{2} - 34 m + 21 = 0

Solve with the quadratic formula

m_{1, 2} = \frac{- ( - 34 ) \pm ( - 34 ) ^{2} - 4 \cdot 9 \cdot 21}{2 \cdot 9}

(- 34)^{2} - 4 \cdot 9 \cdot 21 = 20

m_{1, 2} = \frac{- ( - 34 ) \pm 20}{2 \cdot 9}

Separate the solutions

m_{1} = \frac{- ( - 34 ) + 20}{2 \cdot 9}, m_{2} = \frac{- ( - 34 ) - 20}{2 \cdot 9}

m = \frac{- ( - 34 ) + 20}{2 \cdot 9} : 3

m = \frac{- ( - 34 ) - 20}{2 \cdot 9} : \frac{7}{9}

The solutions to the quadratic equation are:

m = 3, m = \frac{7}{9}

5 x - 9 < - 15 + 8 x

7 x^{3} + x^{2} - 28 x - 4

ln (10)

2 ∣ x + 8 ∣ - 6 = 4

3 x^{3} + 4 x^{2} - 6 x - 8
