2 x^{2} - 3 x = - 5

x = \frac{3}{4} + i \frac{31}{4}, x = \frac{3}{4} - i \frac{31}{4}

Solution steps

2 x^{2} - 3 x = - 5

Move

5

to the left side

2 x^{2} - 3 x + 5 = 0

Solve with the quadratic formula

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

Simplify

(- 3)^{2} - 4 \cdot 2 \cdot 5 : 31 i

x_{1, 2} = \frac{- ( - 3 ) \pm 31 i}{2 \cdot 2}

Separate the solutions

x_{1} = \frac{- ( - 3 ) + 31 i}{2 \cdot 2}, x_{2} = \frac{- ( - 3 ) - 31 i}{2 \cdot 2}

x = \frac{- ( - 3 ) + 31 i}{2 \cdot 2} : \frac{3}{4} + i \frac{31}{4}

x = \frac{- ( - 3 ) - 31 i}{2 \cdot 2} : \frac{3}{4} - i \frac{31}{4}

The solutions to the quadratic equation are:

x = \frac{3}{4} + i \frac{31}{4}, x = \frac{3}{4} - i \frac{31}{4}

5 x^{2} + 7 = 27

0 = - x^{2} + 5 x - 4

2 n^{2} + 15 n + 7 = 0

x^{2} + m x + 7 = 0, m > 0

3 x^{2} - x = - 2
