Answer:
(z−5)(z−5)
Step-by-step explanation:
Let's factor z2−10z+25
z2−10z+25
The middle number is -10 and the last number is 25.
Factoring means we want something like
(z+_)(z+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get -10
Multiply together to get 25
Can you think of the two numbers?
Try -5 and -5:
-5+-5 = -10
-5*-5 = 25
Fill in the blanks in
(z+_)(z+_)
with -5 and -5 to get...
(z-5)(z-5)

Ty for the free points lol
Answer:
2/15+3/15. = (5×2)+(15×3)/15×5 = 10+45/75=55/75 ÷5=11/15
Step-by-step explanation:
First I do it as separate equations 2x-7=0 and 5x+3=0. In this equation you get two answers so you first answer 2x-7=0
2x-7=0
+7 +7
2x=7
/2 /2
x=7/2
Then do 5x+3=0
-3 -3
5x=-3
/5 /5
x= -3/5
Then you can check by putting them back in.
