SOLUTION: Write a quadratic equation having the given numbers as solutions. 3/5 , -9 Is this correct? x=3/5 or x=-9 5x=3 or x+9=0 5x-3=0 or x+9=0 Quadratic equation is: (5x-3)(x

Question 313193: Write a quadratic equation having the given numbers as solutions.
3/5 , -9
Is this correct? x=3/5 or x=-9
5x=3 or x+9=0
5x-3=0 or x+9=0

Quadratic equation is:
(5x-3)(x+9)=0
5x^2+45x-3x-27=0
5x^2+42x-27=0
Or do I set
x^2=3/5 and x=-9
then put it into the quadratic formula ax^2+bx+c=0?

What's above is correct.
Or do I set
x^2=3/5 and x=-9 ********* No, that won't work
then put it into the quadratic formula ax^2+bx+c=0?
