(x) = x^{2} - 4 x + 3

x = \frac{5 + 13}{2}, x = \frac{5 - 13}{2}

Decimal

x = 4.30277 \dots, x = 0.69722 \dots

Solution steps

(x) = x^{2} - 4 x + 3

Refine

x = x^{2} - 4 x + 3

Switch sides

x^{2} - 4 x + 3 = x

Move

x

to the left side

x^{2} - 5 x + 3 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 5 ) \pm ( - 5 ) ^{2} - 4 \cdot 1 \cdot 3}{2 \cdot 1}

(- 5)^{2} - 4 \cdot 1 \cdot 3 = 13

x_{1, 2} = \frac{- ( - 5 ) \pm 13}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 5 ) + 13}{2 \cdot 1}, x_{2} = \frac{- ( - 5 ) - 13}{2 \cdot 1}

x = \frac{- ( - 5 ) + 13}{2 \cdot 1} : \frac{5 + 13}{2}

x = \frac{- ( - 5 ) - 13}{2 \cdot 1} : \frac{5 - 13}{2}

The solutions to the quadratic equation are:

x = \frac{5 + 13}{2}, x = \frac{5 - 13}{2}

9 x^{2} = 4 x + 1

y, y^{2} - 3 y - 4 = 0

2 m^{2} - 7 m = 15

11 - 4 x^{2} = 187

x^{2} - x - 42 = 0
