5x^2 + 9x = -4

What is the “c” value for the following quadratic equation.

c=4

Step-by-step explanation:

5x^2 + 9x = -4

We need to write this in the form

ax^2 +bx+c = 0

So add 4 to each side

5x^2 + 9x+4 = -4+4

5x^2 + 9x+4 = 0

a =5   b=9 and c =4

whatare you sayig

step-by-step explanation:

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
