Question

5x^2-7x=0

Answer 1

we need help badly :/

Answer 2

x=7/5 , 0

Answer 3

how did you get that answer?

Answer 4

we?? need help?

Answer 5

factor out x to get x(5x-7)=0
this means that either x=0 or 5x-7 =0

Answer 6

factor the equation

(x)(5x-7) = 0 we know that anything times 0 = 0 right?

Answer 7

yes

Answer 8

0(5x-7) = 0

(x)(0) = 0 2 options

Answer 9

makes sense?

Answer 10

yall must be typing on Internet explorer :)

Answer 11

a little were confused cause of the squared

Answer 12

5x^2-7x=0
you factor out x. So you get:
x(5x-7)=0.
Then you have two solutions which are:
x=0 and 5x-7=0
you have x=0 solve. now you have to solve the second part which is 5x-7=0, which we get
5x=7..then we divide by 5 to 7 which we end up getting
x=7/5.
so your answers are x=0 and x=7/5

Answer 13

yeah we are but we are trying to do the answer

Answer 14

i had to switch to firefox; less buggy in this site

Answer 15

yes

Answer 27

Answer 29

5x^2-8x+3=0

Answer 30

x- /5 ; x- /5

5(3) = 15

1,15; 3,5 = 8

x- 3/5 ; x- 5/5

5x-3 ; x-1

x = 1 and x = 3/5

Answer 31

georgia math lol

Answer 32

sister got distracted by a butterfly ...hurry up

Answer 33

i dont get it

Answer 34

dont get what?

Answer 35

5x^2-8x+3=0
first we have to factor the whole problem which we get
(5x-3)(x-1)=0, then we have again two solutions which are

5x-3=0 and x-1=0

now lets solve 5x-3=0.
which we get 5x=3 and then divive 5 to 3 which we get x=3/5

now we solve for x-1=0.
we get x=1.

we are done so out two solutions are
x=3/5 and x=1

Answer 36

my method or the answer?

Answer 37

your method

Answer 38

lol..... if it can factor into integers; my method will get to it everytime :)

Answer 39

LOL THEIR SWARMING THE PRETTY GIRL XD

Answer 40

i use the clues that are given in the equation to narrow my options

Answer 41

3y^2+5y=2

Answer 42

ihave an option; either divide that 5 out to begin with or do it in the end; i choose to wait til the end

Answer 43

newton yuou explain better then my teacher

Answer 44

3y^2 +5y -2 = 0

split it up into its form..... set it up

y y

the last number has a sign that tells yuou to add or subtract... -2 means subtract gonna be a + and a -

y+ y-

gonna need to divide that three but do it at the end...

y+ /3 ; y- /3

Answer 45

multiply 1st and last number to get option for the middle

3(2) = 6....factor the 6

1,6 well, 6-1=5 so thats what are middle number needs to be

y+6/3 ; y-1/3 reduce

Answer 46

y+2 ; y-1/3 we can stop here to get the zeros or continue to the final form...if theres a fraction left over, stick the bottom of it in front like this:

y+2 ; 3y-1

y = -2; y= 1/3

Answer 47

if it dont factor like this; you should either complete the square method; or quadratic formula ..
