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: b
Step-by-step explanation:
Answer:
Parallel
Step-by-step explanation:
These 2 lines are parallel because they have the same slope (7).
Answer: y = x² - 6x - 16
<u>Step-by-step explanation:</u>
Given: x = 8, x = -2
--> (x - 8) = 0 , (x + 2) = 0
(x - 8)(x + 2) = 0
y = (x - 8)(x + 2)
y = x² - 6x - 16
