find all vertical asymptotes of the following function. $f(x)=\frac{x - 4}{2x^{2}+34x + 140}$ answer attempt 2 out of 6
Answer
Explanation:
Step1: Set denominator equal to 0
$2x^{2}+34x + 140=0$
Step2: Divide by 2
$x^{2}+17x + 70=0$
Step3: Factor the quadratic
$(x + 7)(x+ 10)=0$
Step4: Solve for x
$x=-7$ or $x=-10$
Answer:
$x=-7,x = - 10$
