Answer: No real solutions
Note: this is assuming you haven't reached complex numbers yet
=============================================================
Explanation:
The given equation 13u^2+23u = -112 is the same as 13x^2+23x = -112
and we can add 112 to both sides getting 13x^2+23x+112 = 0
We see the equation is in the form ax^2+bx+c = 0
The discriminant is
D = b^2 - 4ac
D = 23^2 - 4(13)(112)
D = -5295
The negative discriminant means there are no real number solutions.
-----------
Extra info:
If D = 0, then there would be exactly one real number solution.
If D > 0, then there would be two distinct real number solutions.
Answer:
it is complex solution
no real number solution
Step-by-step explanation:
13u²+23u=-112
13u²+23u+112=0
a=13, b=23 , c=+112
u= (-b±√(b²-4ac))/2a
u=[(-23±√(23)²-4(13)(112)]/2(13)
u=(-23±√-5295)/26
u=(-23±i√5295)/26
