Answer:

First you substitute b for -6.

-6 + 7 = -1

Then you substitute a for -4

2× -4 = -8

Now you have -1/-8, but because they are both negative the solution becomes positive

PLS HELP.... If 4x^2 + bx + 9 = 0, where b is the constant, has exactly one solution, what is a possible value of b ?
IgorLugansk [536]
You can use the discriminant rule, which is :
b^2 -4ac
“exactly one solution” means that it is equal to zero
so:
b^2 -4(4)(9)=0
b^2 -4(36)=0
b^2 -144=0
b^2=144
square root both sides
b=12 or -12

hope this helps !
