Question

factor: x^2-5x+1=0

Answer 1

Are you sure that's the right problem?

Those factors are going to be ugly. You should probably just find them with the quadratic formula and write the thing as factors. That's what I'd do, anyway.

Answer 2

Or you can do middle term beaking!

Answer 3

Breaking*

Answer 4

how?

Answer 5

do middle term of 5

Answer 6

5x

Answer 7

what does this sign (^) represents? x,square?

Answer 8

its actually -5x and im so confused I thought we had to find 2 numbers that add up to -5 and when multiplied give you +1??? idk im so lost

Answer 9

yep

Answer 10

the sign ^ represents the square root of

Answer 11

or you can use "complete the square" method

Answer 12

how?

Answer 13

Its actually called "completing the "square: divide the coefficient of x by 2 and square it! : x^2-5x+25/4-25/4+1=0 , (x-5/2)^2-21/4=0
, (x-5/2)^2=21/4 , x-5= ±√21/4 , x= 5±√21/4

Answer 14

thanks I get it

Answer 15

factors are not always whole numbers! When ur stuck, use the quadratic formular...
