Question

x^2-7x+9 by factoris ​

Answer 1

Answer:

(x-3)²

Step-by-step explanation:

x²-7x+9

now

(a-b)²=a²-2ab+b²

(x)²-2(x)(3)+(3)²

then

a=x

and

b=3

so

(x-3)²

Answer 2

Answer:

I think the question needs to be corrected:

The question is :X^2-6X+9

THE ANSWERS ARE:X=3,3

Step-by-step explanation:

X^2-6X+9

Product of x^2 coefficient and constant is "9"

prime factorization is 3×3

x^2-3x-3x+9=0

x(x-3) -3(x-3)=0

(x-3)(x-3)=0

x-3=0

x=3
