Answer :
There are infinite solution of y.
Step-by-step explanation:
Given,
y = [tex]x^2[/tex] - 10x + 25
To find, the total number of solutions = ?
∴ y = [tex]x^2[/tex] - 10x + 25
⇒ y = [tex]x^2[/tex] - 2(x)(5) + [tex]5^2[/tex]
⇒ y = [tex](x-5)^{2}[/tex]
There are infinite solution of y.
Thus, there are infinite solution of y.
