Answer:
Let's factor x2+3x−18
x2+3x−18
The middle number is 3 and the last number is -18.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get 3
Multiply together to get -18
Can you think of the two numbers?
Try -3 and 6:
-3+6 = 3
-3*6 = -18
Fill in the blanks in
(x+_)(x+_)
with -3 and 6 to get...
(x-3)(x+6)
Answer:
(x−3)(x+6)
Step-by-step explanation:
Answer:
243 .....................
Since the two consecutive integers are even, one of them will be represented by x and one will be x + 2.
x + (x + 2) = 226 Combine like terms
2x + 2 = 226 Subtract 2 from both sides
2x = 224 Divide
x = 112
The two integers are 112 and 114. You can double check by them
112 + 114 = 226
