2 x^{2} - 13 x + 21 = 0

x = \frac{7}{2}, x = 3

Decimal Notation

x = 3.5, x = 3

Solution steps

2 x^{2} - 13 x + 21 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 13 ) \pm ( - 13 ) ^{2} - 4 \cdot 2 \cdot 21}{2 \cdot 2}

(- 13)^{2} - 4 \cdot 2 \cdot 21 = 1

x_{1, 2} = \frac{- ( - 13 ) \pm 1}{2 \cdot 2}

Separate the solutions

x_{1} = \frac{- ( - 13 ) + 1}{2 \cdot 2}, x_{2} = \frac{- ( - 13 ) - 1}{2 \cdot 2}

x = \frac{- ( - 13 ) + 1}{2 \cdot 2} : \frac{7}{2}

x = \frac{- ( - 13 ) - 1}{2 \cdot 2} : 3

The solutions to the quadratic equation are:

x = \frac{7}{2}, x = 3

- \frac{1}{2} - \frac{1}{3}

(5^{2})^{\frac{3}{2}}

∣ 11 y + 4 ∣ > 0

z - 35 = 62

6 x^{2} - 19 x + 19 = 5
