Answer:
if i got you question right then its x=(-13/7) x=(-3/(2+b))
Step-by-step explanation:
to find the roots you need to make it equal to 0.
(x+6x+13)(2x+bx+3) =0
(7x+13)((2+b)x+3) =0
now there are 2 cases:
-> 7x+13=0 7x=(-13) x=(-13/7) solved
-> (2+b)x+3=0 (2+b)x=(-3) x=(-3/(2+b)) solved

Answer:
x = 4.5 x = .5
Step-by-step explanation:
|2x - 5| = 4
The absolute value has two solutions one positive and one negative
2x-5 = 4 2x-5 = -4
Add 5 on each side
2x-5+5 = 4+5 2x-5+5 = -4+5
2x = 9 2x =1
Divide by 2
2x/2 =9/2 2x/2 = 1/2
x = 4.5 x = .5
