There must be two binomial factors. Thus, we eliminate Answer A, which contains only one such factor.
(x-3)(x+3) has the form (a-b)(a+b), which equals a^2 - 3^2. This is a special product. Eliminate Answer B, because a^2 - 3^2 does not equal x^2 - 6x + 9.
The middle term of x^2 - 6x + 9 is negative. This quadratic has the form x^2 - y^2, which is special product and whose factors are (x-y) and (x-y).
Thus, x^2-6x+9 = (x-3)(x-3) (Answer C)
I got x=8
Because 5-6=-1….. 7- -1= 8…… then it’s just that.I
I don’t understand the answers given tho but that’s my guess

Step-by-step explanation:
11x450=4950x
53x450=23850
4950x+23850
216x775=167400
ANSWER:
4950x+23850
____________
167400
Answer:
B.
Step-by-step explanation:
