How do you solve algebraic expressions? Secret to success: Think of what applicable math you could use to solve the problem, do one step at a time, and try each technique until you find one that works! This equals, $$({8-i}/{3-2i})({3+2i}/{3+2i})={24+16i-3+(-i)(2i)}/{(3^2)-(2i)^2}$$, Since $i^2=-1$, this last fraction can be reduced simplified to, $$ {24+16i-3i+2}/{9-(-4)}={26+13i}/{13}$$. Now we can plug in all the possible answers. Each math subsection is arranged in order of ascending difficulty (where the longer it takes to solve a problem and the fewer people who answer it correctly, the more difficult it is). A) $x-5$ is a factor of $p(x)$.B) $x-2$ is a factor of $p(x)$.C) $x+2$ is a factor of $p(x)$.D) The remainder when $p(x)$ is divided by $x-3$ is $-2$. 4 children get 1 apple each while the fifth child gets the basket with the remaining apple still in it.
