simplify sqrt(4)-sqrt(-98)-sqrt(144)+sqrt(-128)

simplify

4 - - 98 - 144 + - 128

- 10 + 2 i

Solution steps

4 - - 98 - 144 + - 128

4 = 2

- 98 = 2 \cdot 7 i

144 = 12

- 128 = 82 i

= 2 - 2 \cdot 7 i - 12 + 82 i

Group like terms

= - 2 \cdot 7 i + 82 i + 2 - 12

Add similar elements:

- 2 \cdot 7 i + 82 i = 2 i

= 2 i + 2 - 12

Subtract the numbers:

2 - 12 = - 10

= 2 i - 10

Rewrite in standard complex form:

- 10 + 2 i

= - 10 + 2 i

\frac{- 2 x ^{2} + 4}{4 - x ^{2}}

\frac{1}{2} \cdot 2 x

(2)^{2} + (1)^{2}

(t - 5)^{2}

30 \times 4
