y=x%5E2-6x%2B5.....set y=0 to find x-intercept

0=x%5E2-6x%2B5....use quadratic formula
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x+=+%28-%28-6%29+%2B-+sqrt%28+%28-6%29%5E2-4%2A1%2A5+%29%29%2F%282%2A1%29+
x+=+%286+%2B-+sqrt%28+36-20+%29%29%2F2+
x+=+%286+%2B-+sqrt%28+16+%29%29%2F2+
x+=+%286+%2B-+4%29%2F2+
x+=+%286+%2B+4%29%2F2+
x+=+10%2F2+
x+=+5+....first x-intercept

x+=+%286+-4%29%2F2+
x+=+2%2F2+
x+=+1+......second x-intercept

now, set x=0 and find y-intercept

y=0%5E2-6%2A0%2B5
y=5..........y-intercept

let's see it on a graph:
