h^{2} + 3 h = 30

h = \frac{- 3 + 129}{2}, h = \frac{- 3 - 129}{2}

Decimal Notation

h = 4.17890 \dots, h = - 7.17890 \dots

Solution steps

h^{2} + 3 h = 30

Move

30

to the left side

h^{2} + 3 h - 30 = 0

Solve with the quadratic formula

h_{1, 2} = \frac{- 3 \pm 3 ^{2} - 4 \cdot 1 \cdot ( - 30 )}{2 \cdot 1}

3^{2} - 4 \cdot 1 \cdot (- 30) = 129

h_{1, 2} = \frac{- 3 \pm 129}{2 \cdot 1}

Separate the solutions

h_{1} = \frac{- 3 + 129}{2 \cdot 1}, h_{2} = \frac{- 3 - 129}{2 \cdot 1}

h = \frac{- 3 + 129}{2 \cdot 1} : \frac{- 3 + 129}{2}

h = \frac{- 3 - 129}{2 \cdot 1} : \frac{- 3 - 129}{2}

The solutions to the quadratic equation are:

h = \frac{- 3 + 129}{2}, h = \frac{- 3 - 129}{2}

2 (x - 6)^{2} + 10 = 20

5 = x^{2} - 4 x

4 p^{2} + 19 p + 12 = - 5

8 y^{2} - 24 y = 0

x, f (x + 2) = x^{2} - 2 x + 5
