Answer:
(a + b + c)(a + b - c)
Step-by-step explanation:
(a + b)² - c² ← is a difference of squares and factors in general as
x² - y² = (x + y)(x - y)
Here x = a + b and y = c , then
(a + b)² - c²
= (a + b + c)(a + b - c)
Answer:
(2, 1).
Step-by-step explanation:
f(x)=2x^2-8x+9
Find -b/2a first, it's -(-8)/2(2)=8/4=2.
Then find the y-coordinate of the vertex.
2(2)^2-8(2)+9=2(4)-16+9=8-16+9=-8+9=1

Step-by-step explanation:
Answer:
Conversely, if n is divisible by 5, then n is the sum of five consecutive integers. In particular, this gives n = 5m + 10 = 5(m + 2) and, since m + 2 is an integer, this shows n is divisible by 5
