Answer

Zeros $-\frac{1}{3},\frac{5}{2}$. x-intercept(s) $-\frac{1}{3},\frac{5}{2}$.

Work Step by Step

Step 1. Zeros $6x^2-13x-5=0 \longrightarrow (2x-5)(3x+1)=0 \longrightarrow x=-\frac{1}{3},\frac{5}{2}$. Step 2. The x-intercept(s) are the same as the zeros, that is $x=-\frac{1}{3},\frac{5}{2}$.
