I think this is the answer good luck
Answer: x = ± i , x = ±√2i are solution .
Step-by-step explanation:
Given :
, use u substitution to solve.
To find : what are the solutions of the equation .
Solution : We have given that
.
Let consider
= u .
Substitute u =
in given equation .
.
On factoring
.
Taking common
u( u+2) +1 (u+2) = 0.
On grouping
(u+1) (u+2) =0
Now, u+1 = 0 ⇒ u = -1.
u+2 = 0 ⇒ u = -2.
In term of x, plugging
= u.
= -1 ;
= -2.
taking square root both side
x = ± i
x = ±√2i.
Therefore, x = ± i , x = ±√2i are solution .
I think it would be 1/2. Because, there's a 50/50 chance of it landing in either side.
Answer:
b = 5
Step-by-step explanation:
0.3x^2 + 5x - 7 = 0
ax^2 + bx + c is the general form of a parabola
a = ,3
b = 5
c = -7
