To find the zeros of function f, find the solutions of the equation f(x)=0 :(2x3−5x2)+(−8x+20)=0x2(2x−5)−4(2x−5)=0(2x−5)(x2−4)=0(2x−5)(x−2)(x+2)=0​Setting each factor equal to 0 yields x=−2,2, and 25​.The zeros of the function are −2,2, and 25​ The zeros of function f correspond to the x-intercepts of its graph in the xy-plane.
