How do you find the x-intercepts and y-intercepts of trinomials. E. g. (x^2-10x+25) How do you find the x-intercepts and y-intercepts of trinomials. E. g. (x^2-10x+25)

The x-intercepts are where the graph crosses the x-axis, and the y - intercepts are where the graph crosses the y-axis. We find these intercepts when we set one variable to zero. For instance,

y = x^2-10x+25

y-intercept : y = 0^2-10 (0) + 25

y = 25

x-intercept: 0 = x^2-10x+25

0 = (x - 5) (x - 5)

x = 5
