Question

write the expression (5 - 2i) - 2(3 + i )is a complex number in a standard form​

Answer 1

Answer:

= -3/

2-i

= (-3)*(2+i)/

(2-i)*(2+i)

= -3 * 2 + (-3) * i/

2 * 2 + 2 * i + (-i) * 2 + (-i) * i

= -6-3i/

4+2i-2i-i2

= -6-3i/

4+2i-2i+1

= -6 +i(-3)/

4 + 1 +i(2 - 2)

= -6-3i/

5

= -1.2-0.6i

Answer 2

Answer:

The Standard from of (5 - 2i ) - 2(3 + i ) is - ( 1 + 4i )

Explanation:

(5 - 2i ) - 2(3 + i )

= 5 - 2i - 6 - 2i

= - 1 - 4i

= -( 1 + 4i )
