For the rational equation, x^2+5x+6/x+3=1 , what is a valid value of x? .

B. -1

Step-by-step explanation:

We have the equation, .

Now, factorizing the polynomial , we get that the factors of the polynomial are (x+3) and (x+2).

So, we get,

i.e.

i.e. x + 2 = 1

i.e. x = -1.

Hence, we get that the value of x is -1.

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
