simplify (3-sqrt(-5))(1+sqrt(-1))

simplify

(3 - - 5) (1 + - 1)

(3 + 5) + (3 - 5) i

Solution steps

(3 - - 5) (1 + - 1)

- 5 = 5 i

= (3 - 5 i) (1 + - 1)

Apply imaginary number rule:

- 1 = i

= (3 - 5 i) (1 + i)

Apply FOIL method

(3 - 5 i) (1 + i) : 3 + i (3 - 5) + 5

= 3 + i (3 - 5) + 5

Rewrite in standard complex form:

(3 + 5) + (3 - 5) i

= (3 + 5) + (3 - 5) i

8^{- \frac{1}{2}}

\frac{( a ^{2} - b ^{2} )}{a + b}

2 x (x - 3) = 7 x^{2} - 7 x

\frac{4 z}{x} \cdot \frac{5 x}{2 a}

- 7.5 a \geq 15
