m-n = 12i + 5 .
m x n = - 35i² - 27i - 6.
A linear equation only has one or two variables. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction. When you find pairs of values that make a linear equation true and plot those pairs on a coordinate grid, all of the points lie on the same line.
given data
m = 3 + 7i
n = -2- 5i
find out
(a) m - n
(b) m x n
for a.
m-n = (3 + 7i) - (-2- 5i)
m-n = 3 + 7i + 2 + 5i
m-n = 12i + 5 .
for b.
m x n = (3 + 7i) × (-2- 5i)
m x n = 3((-2- 5i) + 7i (-2- 5i)
m x n = -6 -15i - 12i - 35i²
m x n = - 35i² - 27i - 6
