720x-720-(i*40)x+120x+10(720-72x)=0

720 x - 720 - (i \cdot 40) x + 120 x + 10 (720 - 72 x) = 0

x = - \frac{243}{5} - i \frac{81}{5}

Solution steps

720 x - 720 - (i 40) x + 120 x + 10 (720 - 72 x) = 0

Remove parentheses:

(a) = a

720 x - 720 - i 40 x + 120 x + 10 (720 - 72 x) = 0

Group like terms

- 40 i x + 720 x + 120 x + 10 (- 72 x + 720) - 720 = 0

Add similar elements:

720 x + 120 x = 840 x

- 40 i x + 840 x + 10 (- 72 x + 720) - 720 = 0

Move

720

to the right side

- 40 i x + 840 x + 10 (- 72 x + 720) = 720

Expand

10 (- 72 x + 720) : - 720 x + 7200

- 40 i x + 840 x - 720 x + 7200 = 720

Add similar elements:

840 x - 720 x = 120 x

- 40 i x + 120 x + 7200 = 720

Move

7200

to the right side

- 40 i x + 120 x = - 6480

Factor

- 40 i x + 120 x : 40 (- i + 3) x

40 (- i + 3) x = - 6480

Divide both sides by

40 (- i + 3)

x = - \frac{243}{5} - i \frac{81}{5}

7 x^{2} + 14 x - 1 = 0

5 x^{2} + 30 x + 25 = 0

\frac{1 0 ^{- 2} x ^{- 4}}{y ^{0}}

\frac{1}{100} (x - 2)^{2} \leq 0

1 6^{\frac{1}{4}}
