- 0.5 x^{2} + 2 x + 11 = - x + 3

x = - 2, x = 8

Solution steps

- 0.5 x^{2} + 2 x + 11 = - x + 3

Multiply both sides by

10

- 5 x^{2} + 20 x + 110 = - 10 x + 30

Move

30

to the left side

- 5 x^{2} + 20 x + 80 = - 10 x

Move

10 x

to the left side

- 5 x^{2} + 30 x + 80 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 30 \pm 3 0 ^{2} - 4 ( - 5 ) \cdot 80}{2 ( - 5 )}

3 0^{2} - 4 (- 5) \cdot 80 = 50

x_{1, 2} = \frac{- 30 \pm 50}{2 ( - 5 )}

Separate the solutions

x_{1} = \frac{- 30 + 50}{2 ( - 5 )}, x_{2} = \frac{- 30 - 50}{2 ( - 5 )}

x = \frac{- 30 + 50}{2 ( - 5 )} : - 2

x = \frac{- 30 - 50}{2 ( - 5 )} : 8

The solutions to the quadratic equation are:

x = - 2, x = 8

e^{2 + 4 i}

(5)^{2}

7 r^{3} - 35 r^{2} + 6 r - 30

∣ x - 7 ∣ = 1

- 2 + \frac{3}{2}
