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

Ithink the answer is b i hope it my friend message me if i’m wrong and i’ll change my answer and fix it for you
