x^{2} - 1.4 x + 0.45 = 0

x = \frac{9}{10}, x = \frac{1}{2}

Decimal Notation

x = 0.9, x = 0.5

Solution steps

x^{2} - 1.4 x + 0.45 = 0

Multiply both sides by

100

100 x^{2} - 140 x + 45 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 140 ) \pm ( - 140 ) ^{2} - 4 \cdot 100 \cdot 45}{2 \cdot 100}

(- 140)^{2} - 4 \cdot 100 \cdot 45 = 40

x_{1, 2} = \frac{- ( - 140 ) \pm 40}{2 \cdot 100}

Separate the solutions

x_{1} = \frac{- ( - 140 ) + 40}{2 \cdot 100}, x_{2} = \frac{- ( - 140 ) - 40}{2 \cdot 100}

x = \frac{- ( - 140 ) + 40}{2 \cdot 100} : \frac{9}{10}

x = \frac{- ( - 140 ) - 40}{2 \cdot 100} : \frac{1}{2}

The solutions to the quadratic equation are:

x = \frac{9}{10}, x = \frac{1}{2}

(x + 1)^{2} - 2 = 0

x^{2} - 12 x - 5 = 0

x^{2} - 12 x - 5 = 7

36 = \frac{x ^{2} - x}{2}

4 x^{2} - 16 x + 4 = 0
