- x^{2} + 160 x - 900 = 0

x = 10 (8 - 55), x = 10 (8 + 55)

Decimal Notation

x = 5.83801 \dots, x = 154.16198 \dots

Solution steps

- x^{2} + 160 x - 900 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 160 \pm 16 0 ^{2} - 4 ( - 1 ) ( - 900 )}{2 ( - 1 )}

16 0^{2} - 4 (- 1) (- 900) = 2055

x_{1, 2} = \frac{- 160 \pm 20 55}{2 ( - 1 )}

Separate the solutions

x_{1} = \frac{- 160 + 20 55}{2 ( - 1 )}, x_{2} = \frac{- 160 - 20 55}{2 ( - 1 )}

x = \frac{- 160 + 20 55}{2 ( - 1 )} : 10 (8 - 55)

x = \frac{- 160 - 20 55}{2 ( - 1 )} : 10 (8 + 55)

The solutions to the quadratic equation are:

x = 10 (8 - 55), x = 10 (8 + 55)

3 x^{2} + a x = a^{2}

7 x^{2} - 3 = - 11

4 (x^{2} - 5) + 5 = - 3

14 x^{2} - 108 x + 144 = 0

4 x^{2} + 17 = 20 x
