r^{2} - 3 r = 0

r = 3, r = 0

Solution steps

r^{2} - 3 r = 0

Solve with the quadratic formula

r_{1, 2} = \frac{- ( - 3 ) \pm ( - 3 ) ^{2} - 4 \cdot 1 \cdot 0}{2 \cdot 1}

(- 3)^{2} - 4 \cdot 1 \cdot 0 = 3

r_{1, 2} = \frac{- ( - 3 ) \pm 3}{2 \cdot 1}

Separate the solutions

r_{1} = \frac{- ( - 3 ) + 3}{2 \cdot 1}, r_{2} = \frac{- ( - 3 ) - 3}{2 \cdot 1}

r = \frac{- ( - 3 ) + 3}{2 \cdot 1} : 3

r = \frac{- ( - 3 ) - 3}{2 \cdot 1} : 0

The solutions to the quadratic equation are:

r = 3, r = 0

9 a^{2} = 81

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

2 x^{2} - 4 x + 8 = 5 x^{2} + 2 x - 5

2 (x + 1)^{2} - 3 = 95

5 x^{2} - 19 x = - 12
