Answer:
below
Step-by-step explanation:
-3x² + 6x + 6 = 0
x = (-b±√(b²-4ac))/2a
x = (-6±√(36 - 4(-3)(6)))/2(-3)
x = (-6±√108)/-6
x = 1 ± √3
The negative solution is not reasonable for he threw it forwards
It’s 0.5, 0.7, 0.25, and 1
Answer:
see below
Step-by-step explanation:
z1 = sqrt(3) -i
z2 = -i
z1+z2 = sqrt(3) -i + -i = sqrt(3) -2i
z1-z2 = sqrt(3) -i - -i = sqrt(3) +-i +i = sqrt(3)
z1*z2 = sqrt(3) -i * -i = sqrt(3)*-i -i*-i = -sqrt(3)i + i^2 = -sqrt(3)i -1
z1/z2 = sqrt(3) -i / -i = sqrt(3)/-i - i/-i = sqrt(3) *i/-i*i +1 = sqrt(3)i/-i^2 +1
= sqrt(3) i +1
