Question

Please help
Simplify. Identify any x-values for which the expression is undefined.
3x+4 over 3x^2+x−4
Answers:
the expression is undefined for x=-4/3 and x=1
1 over x−1
the expression is undefined for x=3/4 and x=-1/2
1 over x+3
the expression is undefined for x=3/4 and x=-1/2
3 over x+1
the expression is undefined for x=-4/3 and x=1
x−1

Answer 1

First, factor the expression 3x^2+x−4 so that we can find values of x that make the denominator equal to zero.

Answer 2

3x^2+x−4 = ( x - 1) * ( ? + ?)

Answer 3

@mantar0078 ^^^^ Need the factors.

Answer 4

How do I find the factors?

Answer 5

Do you recall the factoring of polynomials from Algebra One?

Does this look familiar?

Fill in for the second factor.

3x^2+x−4 = ( x - 1) * ( ? + ?)
