Factorising an equation is putting it into bracket form.
This has square numbers and so needs double brackets
(5x - y) (5x+y)
If you then check this by multiplying the brackets out again you will get:
5x^2 - 5xy + 5xy - y^2
The positive and negative 5xy's cancel each other out and you are left with its original form. Your answer is
(<span>5x - y) (5x+y)</span>
Its b because to simplify radical you multiply by in this instance sqrt of 5 on the denominator and numerator
Step-by-step explanation:
33x
I think it would be 54 degrees
