Answer:
22 - 34i
Step-by-step explanation:
note that i² = - 1
Given
(5 - 4i)(6 - 2i) ← expand factors using FOIL
= 30 - 10i - 24i + 8i²
= 30 - 10i - 24i - 8 ← collect like terms
22 - 34i
In brackets everything has to multiplied by 3. It there is no sign between its always multiply!!!
this means that it has to be
3 x X + 3 x 11
this means that we can also multyplay 3 by 11 now.
and that equals to 33. There fore the expansion will be:
3 x X + 33
we can also simplify 3 x X which would be 3x (as I mentioned before, It there is no sign between its always multiply!!!)
so the expansion for 3(x+11) is 3x + 33
Answer:
g(x) = 17-32x
Step-by-step explanation:
f(x) = 8x-3
g(x) = 5-2(8x-3)2
= 5-4(8x-3)
= 17-32x
Answer: It would be 20
