3x+4/x^2-6x+5= ? /? (x-1)+? /? (x-5)
the answer is:
-7/4(x-1)+ 19/4(x-5)

Step-by-step explanation:

The given rational expression is:

We can use concept of Partial Fractions to solve this problem. Let,

Multiplying both sides by (x - 1)(x - 5), we get:

Substituting x = 5, we get:

Substituting x = 1, we get:

Substituting the value of A and B, back in the original equation, we get:

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
