Answer 2

Given,

z1 = (2,-1)

z2 = (6,3)

To Find,

The value of z1-z2 =?

Solution,

We know from the question that z1 and z2 are complex numbers.

The general form of a complex number is z = a + bi

Therefore, z1 = 2 + (-1)i  = 2 - i ⇒ Equation 1

z2 = 6 + 3i ⇒ Equation 2

Subtracting equation 2 from equation 1

z1 - z2 = 2 - i - (6 + 3i)

z1 - z2 = 2 - i - 6 - 3i

z1 - z2 = 2 - 6 - i - 3i

z1 - z2 = - 4 - 4i

z1 - z2 = (-4,-4)

Hence, if z1 = (2,-1) z2 = (6,3) then z1-z2 is (-4,-4).
