No because it would be
if you knew that
ax^2+bx+c was a trinomial square, then the factored form would be
or
so
if w^2-9w+81 is perfect square, factored form is either
or
aka
or
expand them
(x+9)^2=x^2+18x+81, wron middle term
(x-9)^2=x^2-18x+81 wrong
so it is not
Answer:
7x-5 = 9
x = 2
Step-by-step explanation:
Let x be the number

Divide each side by 7
7x = 14
7x/7 = 14/7
x=2
