b^2-14b+49
(b-7)^2
6m^2-150
6(m^2-25)
6(m-5)(m+5)

Well....the equation(s) are a^2 - b^2=(a+b)(a-b)
It's confusing...i know. So for the first, it'd be (b+7)(b-7) cuz u have to follow the equation and find the perfect square of 49.
For the second, you would have to take out a common factor which would be 3. SO ur equation would read 6(m^2-25)
And since 50 has a perfect square of 5 the answer would be 6(m+5)(m-5) Hope that helps!!

The first one is a perfect square trinomial, and it is factored correctly by one of the other posters.
the second one will be the difference of two squares when you factor out the common 6

you could, that's purely that do it you will choose complicated numbers. Extending the version of two squares: x² - a² = (x - a)(x + a) = (x - ?a²)(x + ?a²) x² + a² = x² - (-a²) = (x - ?(-a²))(x + ?(-a²)) = (x - ai)(x + ai) observe -a² ? (-a)²

Ok what you do first is
oh nevermind! they are both prime. that means that they look like prime rib when you think about them with your eyes closed!
