Find the zero of the polynomial p x 3x
WebJul 20, 2024 · In this example, he used p (x)= (5x^3+5x^2-30x)=0. Using that equation will show us all the places that touches the x-axis when y=0. But if we want to find all the x-value for when y=4 or other real numbers we could use p (x)= (5x^3+5x^2-30x)=4. Simply … WebZeros are when a polynomial function "intersects" or touches the x-axis. When a polynomial is in factored form, like the question in the video, it is very easy to find the zeros. If you think about it, an x-intercept is when a function intersects the x-axis, and for this to be true, the y-value of that coordinate must be equal to zero.
