4 z^{2} - 8 z + 5 = 2

z = \frac{3}{2}, z = \frac{1}{2}

Decimal Notation

z = 1.5, z = 0.5

Solution steps

4 z^{2} - 8 z + 5 = 2

Move

2

to the left side

4 z^{2} - 8 z + 3 = 0

Solve with the quadratic formula

z_{1, 2} = \frac{- ( - 8 ) \pm ( - 8 ) ^{2} - 4 \cdot 4 \cdot 3}{2 \cdot 4}

(- 8)^{2} - 4 \cdot 4 \cdot 3 = 4

z_{1, 2} = \frac{- ( - 8 ) \pm 4}{2 \cdot 4}

Separate the solutions

z_{1} = \frac{- ( - 8 ) + 4}{2 \cdot 4}, z_{2} = \frac{- ( - 8 ) - 4}{2 \cdot 4}

z = \frac{- ( - 8 ) + 4}{2 \cdot 4} : \frac{3}{2}

z = \frac{- ( - 8 ) - 4}{2 \cdot 4} : \frac{1}{2}

The solutions to the quadratic equation are:

z = \frac{3}{2}, z = \frac{1}{2}

\frac{1}{x + h + 1} - \frac{1}{x + 1}
