Step-by-step explanation:
Answer:
2 - 19i
Step-by-step explanation:
note that i² = - 1
given
(3 + 8i)(- 2 - i) ← expand using FOIL
= - 6 - 3i - 16i - 8i²
= - 6 - 3i - 16i - 8(- 1)
= - 6 - 3i - 16i + 8 ← collect like terms
= 2 - 19i
Answer:
Step-by-step explanation:
Taking the succession:
You can multiply and divide by 1-r without chaging the result:
Distributing the upper part of the fraction you have:
As can be seen all the intermediate members will be canceled by a same member with opposite sign, only will be left so:
Answer:
x = - 2
Step-by-step explanation:
Given
y = 4x² + 16x - 18
with a = 4, b = 16 , then the equation of the axis of symmetry is
x = - = - = - 2
