c=x2-3x

Step-by-step explanation:

Let's solve for c.

-x2+3x+c=0

Step 1: Add x^2 to both sides.

-x2+c+3x+x2=0+x2

c+3x=x2

Step 2: Add - 3x to both sides.

c+3x+-3x=x2+-3x

c=x2-3x

Answer:

c=x2-3x

Answer:a quadratic equation has no real number solutions than the discriminant is less than zero

D < 0

(b^2 - 4ac) < 0

(9 - 4 (-1*c) < 0

(9+4c) < 0

4c < - 9

c < - 9/4
