simplify sqrt(25)-sqrt(-98)+sqrt(81)-sqrt(-50)

simplify

25 - - 98 + 81 - - 50

14 - 122 i

Solution steps

25 - - 98 + 81 - - 50

25 = 5

- 98 = 2 \cdot 7 i

81 = 9

- 50 = 2 \cdot 5 i

= 5 - 2 \cdot 7 i + 9 - 2 \cdot 5 i

Group like terms

= - 2 \cdot 7 i - 2 \cdot 5 i + 5 + 9

Add similar elements:

- 2 \cdot 7 i - 2 \cdot 5 i = - 122 i

= - 122 i + 5 + 9

Add the numbers:

5 + 9 = 14

= - 122 i + 14

Rewrite in standard complex form:

14 - 122 i

= 14 - 122 i

2 (x + 4)^{2}

- 8^{- 2}
