I'm stuck:
a. 4(x squared) + 12x + 3 = 0
b. 2x + 1 = 5 divided by (x + 2)
c. [(x + 1) divided by x ] - [x divided by (x + 1)] = 0
Here ya go
using the quadratic formula let a=4, b=12 and c=3 we have
so
you can do the rest.
As for the next one
multiply both sides by (x+2) and then subtract by 5
multiply and simplify
and use the quadratic formula. I'll leave the last one to you
Hint : find a common denominator and then multiply both sides of the equation by it.
