Rule needed: i^2 = -1
Standard form a + bi
(3 + 2i)(7 - 5i) FOIL
3 * 7 = 21
3 * - 5i = - 15i
2i * 7 = 14i
2i * -5i = - 10i^2 = - 10 * -1 = 10
Putting it all back together.
31 - i
A=7 b =4 and c=9 Because the 7 is the base of the number
5(x+3)=7x-3 which is the equation, then we solve for it, and the answer is 9
