Question

4t^2(k+9)7+20ts(k+9)7+25s^2(k+9)7
factored : (k+9)^7(2t-5s)^2
now, will u show me the steps to get these?

Answer 1

You mean this? \[4t^2(k+9)^7+20ts(k+9)^7+25s^2(k+9)^7\]?

Answer 2

Yup.

Answer 3

Well: \[=(k+9)^7(4t^2+20ts+25s^2) \] Got this part?

Answer 4

Yeah.

Answer 5

I know the answer but what's the steps?

Answer 6

Which step you don't understand. From there, you just need to factor 4t^2+20ts+25s^2

Answer 7

Yeah. I mean steps onhow you factored it

Answer 8

Are you sure have written the problem correctly?

Answer 9

YEAH

Answer 10

ok. so what's next with
(k+9)7(4t2+20ts+25s2)

Answer 11

?

Answer 12

Find two numbers A and B where
A*B=4*25=100
A+B=20

Answer 13

and .. ? that's how you get (k+9)7(4t2+20ts+25s2)?
