8th grade math here:
how do u put this in factored form?
y=(x*x) + 9
well im stumped. thanks! :)

The others are correct, it cannot be factorised using 8th grade mathematics. It is not a conventional perfect square like Liz suggests as the 9 must be negative, not positive. Hence you must use complex numbers.

(x-3)(x+3) This problem is a difference of perfect squares. x*x is a perfect square. And nine is a perfect square. This means that because there is a no b term that the problem must be x plus the square root of the second number times x minus the square root of the second number

Factoring in fact skill which you're taking numbers out of the entire expression/equation: So, you will discover the GCF, the terrific trouble-free element, or the quantity that is taken out of the two words, subsequently, 12: 12(a million+2x)

Unless you've been introduced to √-1, you don't.
x^2 + 9 = (x + 3√-1)(x - 3√-1), usually written as
(x + i3)(x - i3)

y=(x*x) + 9. This cannot be factored.
