Factor(ise):
y%5E2-7x%2B10 The factors will be two binomials of the form: (y+m)(y+n) in which m*n = 10 and m+n = -7
Here are a few possibilities:
m=2 and n=5...m*n = 10 and m+n = 7 No good 'cause you need m+n = -7
m = -2 and n = -5 ...m*n = 10 and m+n = -7 Good!, So...
y%5E2-7x%2B10+=+%28y-2%29%28y-5%29
