x^{2} + 3 x - 5 x - 15 = 0

x = 5, x = - 3

Solution steps

x^{2} + 3 x - 5 x - 15 = 0

Refine

x^{2} - 2 x - 15 = 0

Solve with the quadratic formula

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

(- 2)^{2} - 4 \cdot 1 \cdot (- 15) = 8

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

Separate the solutions

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

x = \frac{- ( - 2 ) + 8}{2 \cdot 1} : 5

x = \frac{- ( - 2 ) - 8}{2 \cdot 1} : - 3

The solutions to the quadratic equation are:

x = 5, x = - 3

19 - 2 x > 13

16.2 \cdot 3.51 - \frac{1}{2} \cdot 9.81 \cdot 3.5 1^{2}

2 x^{2} + 3 x - 2

8 n^{3} - 7 n^{2} + 56 n - 49

- 48 - 8 n + n^{2}
