Answer:
3x^2 -7x +2
Step-by-step explanation:
(15x^2 -35x+10) ÷5
(15/5x^2 -35/5x+10/5)
3x^2 -7x +2
This will factor
(3x-1) (x-2)
Answer: subtract 12-4
Step-by-step explanation:
For the range you subtract the smallest number from the biggest number so 12-4.
Answer: (x−2)(x−2)
The middle number is -4 and the last number is 4.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get -4
Multiply together to get 4
Can you think of the two numbers?
Try -2 and -2:
-2+-2 = -4
-2*-2 = 4
Fill in the blanks in
(x+_)(x+_)
with -2 and -2 to get...
(x-2)(x-2)
Answer:
(x−2)(x−2)
so the answer is D.
