I need the following to answer
Step-by-step explanation:
Answer:
f>10
Step-by-step explanation:
f>2*5
Multiply 2 * 5
f>10
No, he is not correct. The lines are the same, so there are an infinite number of solutions.
When two lines are parallel, then the solution is empty set.
Factoring f(x) would give a factor (x-1-2i), so you can divide f(x) by this, leaving (x-3)(x+4)(x-1+2i), so the other roots are:
x=3
x=-4
x=1-2i
