80000 = 100 - 6.25 (x - 9)^{2}

x = 4799 i + 9, x = - 4799 i + 9

Solution steps

80000 = 100 - 6.25 (x - 9)^{2}

Switch sides

100 - 6.25 (x - 9)^{2} = 80000

Move

100

to the right side

- 6.25 (x - 9)^{2} = 79900

Divide both sides by

- 6.25

(x - 9)^{2} = - 12784

For

(g (x))^{2} = f (a)

the solutions are

g (x) = f (a), - f (a)

Solve

x - 9 = - 12784 : x = 4799 i + 9

Solve

x - 9 = - - 12784 : x = - 4799 i + 9

The solutions to the quadratic equation are:

x = 4799 i + 9, x = - 4799 i + 9

t (t + 1) = 3 t^{2} + 1

3 b^{2} = 12

5 x = 18 - x^{2} - 2 x

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

(x + 7) (2 x - 7) = 0
