The required simplification for complex expression (2 + i) - (-3+9i) is 5-8i.
Simplification of (2 + i) - (-3+9i) to be determined.
What is a complex number?
The number that consist of a real number and imaginary numbers is called complex numbers. The standard form of complex number = a + bi. where a is the real part and bi is the imaginary b.
Let Z1 = (2 + i)
Z2 = (-3+9i)
Now
Z1 - Z2 = 2 + i - ( -3 + 9i )
While opening the parenthesis the negative sign outside change the sign presents inside the parenthesis.
Z1 - Z2 = 2 + i + 3 - 9i
Z1 - Z2 = 5 - 8i, it is the required simplification of Z2 - Z1
The required simplification for complex expression (2 + i) - (-3+9i) is 5-8i.
