simplify (5+sqrt(-1))(2-sqrt(-36))

simplify

(5 + - 1) (2 - - 36)

16 - 28 i

Solution steps

(5 + - 1) (2 - - 36)

Apply imaginary number rule:

- 1 = i

= (5 + i) (2 - - 36)

- 36 = 6 i

= (5 + i) (2 - 6 i)

Apply FOIL method

(5 + i) (2 - 6 i) : - 28 i + 16

= - 28 i + 16

Rewrite in standard complex form:

16 - 28 i

= 16 - 28 i

- 2 \cdot 2

\frac{3}{8} + \frac{7}{8}

5 x^{2} - 3 = 42

\frac{( 6 x ^{3} ) ^{0}}{3 x y ^{2}}

10 (4 x + 2) = 3 (8 - x) + 6
