8xsquared = -14x -3

OpenStudy (saifoo.khan):

do u knw factorization method?

OpenStudy (anonymous):

add -14x -3 in both side let the equation equal to 0

OpenStudy (anonymous):

8x^2+14x + 3 =0

OpenStudy (anonymous):

okay, that did seem to hard

OpenStudy (anonymous):

(then u fine the 2 facter of 8 and 3 that add up to 14) the two factor of 8 are 2 nd 4 , and the two factor of 3 is 1 and 3

OpenStudy (anonymous):

u should get (2x+3)(4x + 1)

OpenStudy (anonymous):

understand it?

OpenStudy (anonymous):

(4x-1)(x+2)=4x

OpenStudy (anonymous):

okay.. do you know how to multiply the two binomial?

OpenStudy (anonymous):

okay.. do you know how to multiply the two binomial?
