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>
Answer:
36 mph
Step-by-step explanation:
d = rt
d = (x)(3.6)
d = (x-4)(4)
3.6x = 4x - 16
-0.4x = -16
x = 40
Her speed was 40 on Thursday, so 36 on Friday
3 is greater than -6. Therefore,
-6 < 3.
This is not factorable. It can be easily tested using the radicand expression of the quadratic equation. (Perfect square= Factorable, No Perfect= Not Factorable.)
