2 (x + 5) \cdot x = 300

x = 10, x = - 15

Solution steps

2 (x + 5) x = 300

Expand

2 (x + 5) x : 2 x^{2} + 10 x

2 x^{2} + 10 x = 300

Move

300

to the left side

2 x^{2} + 10 x - 300 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 10 \pm 1 0 ^{2} - 4 \cdot 2 ( - 300 )}{2 \cdot 2}

1 0^{2} - 4 \cdot 2 (- 300) = 50

x_{1, 2} = \frac{- 10 \pm 50}{2 \cdot 2}

Separate the solutions

x_{1} = \frac{- 10 + 50}{2 \cdot 2}, x_{2} = \frac{- 10 - 50}{2 \cdot 2}

x = \frac{- 10 + 50}{2 \cdot 2} : 10

x = \frac{- 10 - 50}{2 \cdot 2} : - 15

The solutions to the quadratic equation are:

x = 10, x = - 15

x^{2} + 0.9 x - 0.36 = 0

x, z (x + y) p + z (x - y) q = x^{2} + y^{2}

(\frac{1}{2}) a (a - 18) = 2480

n (t) = 15 t^{2} - 180 t + 5000

6 x^{2} + (a - 12) x - (a^{2} + a - 6) = 0
