Answer:
B. 3x² +2 = 0
Step-by-step explanation:
The equation of A has a couple of real roots. We're pretty sure there are complex numbers that will satisfy this equation, but we don't know how to find them. (We suspect a typo, and that the equation is supposed to be 2x² +1 = 7x, which has only real roots.)
__
The equation of B can be rewritten as ...
x² = -2/3
This will have complex roots.
__
The discriminants of both equations C and D are positive, so those have only real roots.
2x² -5x -1 ⇒ d = (-5)² -4(2)(-1) = 33
3x² -6x -1 ⇒ d = (-6)² -4(3)(-1) = 48
Answer:
The positive integer is 9
Step-by-step explanation:
6 times a number is 27 less than the square of that number.
Let the number be x
These interpreted means 6 nultiplies by x is 27 less than the square of that number(x^2). F
6x= 27<x^2
0 = 27<-6x+x^2
Look for 2 numbers whose product is 27 and sum is -6
0 = 27<-9x+3x+x^2
0 = -9(3+x)+x(3+x)
0 = (x-9)(3+x)
x-9 = 0 3 + x =0
x= 9 -3 = x
The positive integer is 9
Answer:
10
Step-by-step explanation:
5/6 ÷ 1/12 ➡ 5/6 × 12/1 = 60/6 ➡ 10
