Answer:
see the explanation
Step-by-step explanation:
<u><em>The correct question is</em></u>
Use the discriminant to determine how many solutions are possible for the following equation (show work).
5x^2-3x+4=0
we know that
The discriminant for a quadratic equation of the form
is equal to
If D=0 then the equation has only one real solution
If D>0 then the equation has two real solutions
If D<0 then the equation has no real solutions (two complex solutions)
in this problem we have
so
substitute
so
The equation has no real solutions, The equation has two complex solutions
therefore
I know there are___No____
real solutions to the equation in problem 4 because ___the discriminant is negative___
Answer:
Yes
Step-by-step explanation:
When you simplify 2(x+1). [MULTIPLY]
It comes 2x+1 so it is equivalent to 2x+1
X is less then or equal to 1<u /><em /><u />
