Answer

$\dfrac{3x^{2}+7x+2}{3x^{2}+13x+4}=\dfrac{x+2}{x+4}$

Work Step by Step

$\dfrac{3x^{2}+7x+2}{3x^{2}+13x+4}$ Factor the numerator: $\dfrac{3x^{2}+7x+2}{3x^{2}+13x+4}=\dfrac{(x+2)(3x+1)}{3x^{2}+13x+4}=...$ Factor the denominator and then, simplify: $...=\dfrac{(x+2)(3x+1)}{(x+4)(3x+1)}=\dfrac{x+2}{x+4}$
