Answer:
We conclude that:
Step-by-step explanation:
Given the expression
subtract 3 from both sides
Add -2² to both sides
simplify
Applying the perfect square formula: (a-b)² = a²-2ab+b²
so
∵
Therefore, we conclude that:
Answer:
Uhh? You can't factor this!
Step-by-step explanation:
So.. we see that the last term, the constant, (the +5) is positive, which means the two terms (the a and b on the (x+a)(x+b) must be either both positive or both negative).
We try positive, and we end up with
(x+1)(x+5)
x^2 + x + 5x + 5
x^2 + 6x + 5
which is not what we want!
We try negative, and we end up with
(x-1)(x-5)
x^2 -x -5x +5
x^2 -6x +5
which is also not what we want!
This isn't factorable!
You can always complete the square or utilize the quadratic equation, but you can't factor it.
