Question

factor completely
a^2-10ab+3b^2


and then

5x^2-10x

Answer 1

man you have quite a bit of homework, lol

Answer 2

you dont even know :| lol

Answer 3

these are my last two problems though !!

Answer 4

I dont think the first one can be factored.

Answer 5

oh nice. kk - the 1st is: (a-5b)^2-22b^2
the 2nd is: 5(x-2)x

Answer 6

the first is not factorable

5x^2-10x
5x(x-2)

Answer 7

ohh complete the square thing nice tehmagik!

Answer 8

that first one can be factored even further:
(a-5b)^2-22b^2 = [(a-5b)-bsqrt(22)][[(a-5b)+bsqrt(22)]

Answer 9

wait so is the first one factorable or not?

Answer 10

it is.

Answer 11

can someone show me the steps for the 2nd one i dont understand this at all lol

Answer 12

Okay for the 2nd one:
5x^2-10x
what do u see in common in both terms?

Answer 13

the 5

Answer 14

Or what would u see if I rewrote this as:
x(5x) - 2(5x)

Answer 15

the 5x

Answer 16

yes so take it out:
5x(x-2)

Answer 17

and then factor that or is that the answer?

Answer 18

That's as far as you can factor it. x-2 cannot be factored further, and neither can 5x.
