20 x^{2} - 56 x + 15 = 0

x = \frac{5}{2}, x = \frac{3}{10}

Decimal Notation

x = 2.5, x = 0.3

Solution steps

20 x^{2} - 56 x + 15 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 56 ) \pm ( - 56 ) ^{2} - 4 \cdot 20 \cdot 15}{2 \cdot 20}

(- 56)^{2} - 4 \cdot 20 \cdot 15 = 44

x_{1, 2} = \frac{- ( - 56 ) \pm 44}{2 \cdot 20}

Separate the solutions

x_{1} = \frac{- ( - 56 ) + 44}{2 \cdot 20}, x_{2} = \frac{- ( - 56 ) - 44}{2 \cdot 20}

x = \frac{- ( - 56 ) + 44}{2 \cdot 20} : \frac{5}{2}

x = \frac{- ( - 56 ) - 44}{2 \cdot 20} : \frac{3}{10}

The solutions to the quadratic equation are:

x = \frac{5}{2}, x = \frac{3}{10}

∣ 4 x - 4 ∣ < 8

∣ 2 x - 3 ∣ \leq 1.7
