x^{2} - 3.5 x + 2.5 = 0

x = \frac{5}{2}, x = 1

Decimal Notation

x = 2.5, x = 1

Solution steps

x^{2} - 3.5 x + 2.5 = 0

Multiply both sides by

10

10 x^{2} - 35 x + 25 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 35 ) \pm ( - 35 ) ^{2} - 4 \cdot 10 \cdot 25}{2 \cdot 10}

(- 35)^{2} - 4 \cdot 10 \cdot 25 = 15

x_{1, 2} = \frac{- ( - 35 ) \pm 15}{2 \cdot 10}

Separate the solutions

x_{1} = \frac{- ( - 35 ) + 15}{2 \cdot 10}, x_{2} = \frac{- ( - 35 ) - 15}{2 \cdot 10}

x = \frac{- ( - 35 ) + 15}{2 \cdot 10} : \frac{5}{2}

x = \frac{- ( - 35 ) - 15}{2 \cdot 10} : 1

The solutions to the quadratic equation are:

x = \frac{5}{2}, x = 1

20 x^{2} + 9 x - 18 = 0

(x + 5) (3 x - 5) = 0

b^{2} - 4 b = 0

x^{2} - 6 = 58

x^{2} - 6 = 3 x
