15 = 8 h^{2} - 2 h

h = \frac{3}{2}, h = - \frac{5}{4}

Decimal Notation

h = 1.5, h = - 1.25

Solution steps

15 = 8 h^{2} - 2 h

Switch sides

8 h^{2} - 2 h = 15

Move

15

to the left side

8 h^{2} - 2 h - 15 = 0

Solve with the quadratic formula

h_{1, 2} = \frac{- ( - 2 ) \pm ( - 2 ) ^{2} - 4 \cdot 8 ( - 15 )}{2 \cdot 8}

(- 2)^{2} - 4 \cdot 8 (- 15) = 22

h_{1, 2} = \frac{- ( - 2 ) \pm 22}{2 \cdot 8}

Separate the solutions

h_{1} = \frac{- ( - 2 ) + 22}{2 \cdot 8}, h_{2} = \frac{- ( - 2 ) - 22}{2 \cdot 8}

h = \frac{- ( - 2 ) + 22}{2 \cdot 8} : \frac{3}{2}

h = \frac{- ( - 2 ) - 22}{2 \cdot 8} : - \frac{5}{4}

The solutions to the quadratic equation are:

h = \frac{3}{2}, h = - \frac{5}{4}

a, z = a^{2} - x^{2} - y^{2}

m^{2} + 16 m - 32 = - 7

4 x^{2} + 3 x = 0

9 x^{2} - 3 x + 1 = 0

x^{2} = - 169
