Question

factor completely
25x^2+240x-100

Answer 1

the first step is to divide by the GCF of the coefficients
25 isn't a factor of 240
the GCF is 5
we have
5(5x^2 + 48x - 20)

Answer 2

now you can try to factor the expression in the parentheses)

Answer 3

do u multiply 5 n -20

Answer 4

is the answer 5(x-2)(x+50)

Answer 5

yes - that's a start

Answer 6

right

Answer 7

thank u

Answer 8

yw

Answer 9

can u help again

Answer 10

no that's wrong - (whats wrong with me today!!!!)

Answer 11

5x^4-44x^2+63

Answer 12

Meow. What's going on here? ~

Answer 13

wats wrong with it

Answer 14

tryin to find an answer to a problem

Answer 15

correct is
5(5x - 2)(x + 10)

Answer 16

5x^2 + 48x - 20 can be factored further. That's what's wrong with it @cwrw238

Answer 17

yes

Answer 18

can 5(x^2-13x+42 be factored more

Answer 19

Yes. He just factored it for you.

Answer 20

how do u do that

Answer 21

Ever heard of FOIL or Binomials?

Answer 22

yea

Answer 23

you can factor x^2 - 13x + 42

- you need 2 numbers a and b where ab=42 and a + b = -13

Answer 24

the factors will be of the form (x + a)( x + b)

Answer 25

what factors of 42 will ad up to -13?

Answer 26

5(x-6)(x-7) is that the factored answer

Answer 27

yes

Answer 28

after u do factor n sum on 5(5x^2+48-20) wat do u do

Answer 29

I don't understand that question - and do u mean -48x?

Answer 30

sorry + 48x

Answer 31

just explain (25x^2+240x-20) to me

Answer 32

i mean -100

Answer 33

(25x^2+240x-100)

Answer 34

well first you take out the 5 - do you see that 5 is the greatest common factor of the 3 numbers?

Answer 35

ya wat after that

Answer 36

now you factor
5x^2 + 48x -20

first multiply 5 * -20 = -100

with +48 in mind we see that +50 and -2 are the factors that will fit

so we can write

5x^2 +50x - 2x -20

now factor by grouping:

5x(x + 10) -2(x + 10
= (5x - 2)(x + 10)

Answer 37

ok?

Answer 38

thanks!

Answer 39

ok

Answer 40

with (5x^4-44x^2+63) do u do it the same way
