Just plug it in:
c & d = c² + d² - 4
2 & 1 = 1² + 2² - 4
= 1 + 4 - 4 = 1
Answer:
(x + 8)(x + 3)
Step-by-step explanation:
Step 1: Write quadratic
x² + 11x + 24
Step 2: Factor
We need to find 2 numbers that add up to 11 and multiply to 24.
8 and 3 work; 8 + 3 = 11 8(3) = 24
(x + 8)(x + 3)
Answer:
(-3, -1) (-2, 3)
(-2, 3) (-2, 3)
Step-by-step explanation:
Notice that if
, then
. Recall the definition of the derivative of a function
at a point
:
So the value of this limit is exactly the value of the derivative of
at
.
You have
