14000 = 0.125 x^{2} + 20 x + 5000

x = 200, x = - 360

Solution steps

14000 = 0.125 x^{2} + 20 x + 5000

Multiply both sides by

1000

14000000 = 125 x^{2} + 20000 x + 5000000

Switch sides

125 x^{2} + 20000 x + 5000000 = 14000000

Move

14000000

to the left side

125 x^{2} + 20000 x - 9000000 = 0

Factor

125 x^{2} + 20000 x - 9000000 : 125 (x - 200) (x + 360)

125 (x - 200) (x + 360) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x - 200 = 0 or x + 360 = 0

Solve

x - 200 = 0 : x = 200

Solve

x + 360 = 0 : x = - 360

The solutions to the quadratic equation are:

x = 200, x = - 360

(x - 7)^{2} - 9 = 0

(185) (130 - x) = (266.67) (45 - x)^{2}

f a c t or 3 x^{3} - 15 x^{2}

20 - (6 x + 2) = 10 - 2 (x + 1)

7 x - (x - 12) = 32 - 4 x
