- 4.45 h^{2} - 3.9 h + 0.55 = 0

h = - 1, h = \frac{11}{89}

Decimal Notation

h = - 1, h = 0.12359 \dots

Solution steps

- 4.45 h^{2} - 3.9 h + 0.55 = 0

Multiply both sides by

100

- 445 h^{2} - 390 h + 55 = 0

Solve with the quadratic formula

h_{1, 2} = \frac{- ( - 390 ) \pm ( - 390 ) ^{2} - 4 ( - 445 ) \cdot 55}{2 ( - 445 )}

(- 390)^{2} - 4 (- 445) \cdot 55 = 500

h_{1, 2} = \frac{- ( - 390 ) \pm 500}{2 ( - 445 )}

Separate the solutions

h_{1} = \frac{- ( - 390 ) + 500}{2 ( - 445 )}, h_{2} = \frac{- ( - 390 ) - 500}{2 ( - 445 )}

h = \frac{- ( - 390 ) + 500}{2 ( - 445 )} : - 1

h = \frac{- ( - 390 ) - 500}{2 ( - 445 )} : \frac{11}{89}

The solutions to the quadratic equation are:

h = - 1, h = \frac{11}{89}

3 3^{2} + 13 x + 42

c - 3.5 \leq 3

∣ 1 - 4 x ∣ + 8 = 13

36 - 3 x + 4 - x^{2} = 47 - 2 x^{2} + 9 x

\frac{x + 4}{- 2} \leq \frac{3 x - 8}{3}
